| 5 | Simple Double Hetero[5]helicenes Realize Highly Efficient and Narrowband Circularly Polarized Organic Light-Emitting Diodes显示文摘Helicene-based emitters with unique inherent circularly polarized luminescence(CPL)are promising yet remain a formidable challenge for highly efficient circularly polarized organic light-emitting diodes(CP-OLEDs),ascribed to their tough synthesis,low emission efficiency,and easy racemization in the thermal deposition process.Herein,a pair of helicenebased enantiomers,namely(P)-helicene-BN and(M)-helicene-BN,were developed,which merge helical chirality and the B/N/S inserted polycyclic aromatic framework to concurrently feature CPL and narrow thermally activated delayed fluorescence(TADF)characteristics.Benefiting from the excellent thermal/photophysical/chiroptical properties,the narrowband green CP-OLEDs based on enantiomers achieved maximum external quantum efficiencies(EQE_(max))of up to 31.5%,and dissymmetry factor(|g_(EL)|)of 2.2×10^(−3).This work reveals the great potential of helicene-based emitters in CP-OLEDs. | Wei Yang Nengquan Li Jingsheng Miao Lisi Zhan Shaolong Gong Zhongyan Huang Chuluo Yang | 2022 | CCS Chemistry2022，4，11： | 1 |

Although D-A type emitters have been developed for many years, what makes them in the spotlight is the rise of thermally activated delayed fluorescence (TADF) materials.In 2012, Adachi et al.[1] reported a series of D-A emitters with TADF features to fully utilize electrogenerated excitons. After the pioneer work, numerous TADF materials with D-A structure were extensively explored for the application of organic light emitting diodes (OLEDs)[2]. | Chuluo Yang | 2021 | Science China Chemistry2021，64，2： | 1 |

| 14 | A new perspective to develop regiorandom polymer acceptors with high active layer ductility,excellent device stability,and high efficiency approaching 17%显示文摘The recently reported efficient polymerized small-molecule acceptors(PSMAs)usually adopt a regioregular backbone by polymerizing small-molecule acceptors precursors with a low-reactivity 5-brominated 3-(dicyanomethylidene)indan-1-one(IC)end group or its derivatives,leading to low molecular weight,and thus reduce active layer mechanical properties.Herein,a series of newly designed chlorinated PSMAs originating from isomeric IC end groups are developed by adjusting chlorinated positions and copolymerized sites on end groups to achieve high molecular weight,favorable intermolecular interaction,and improved physicochemical properties.Compared with regioregular PY2Se-Cl-o and PY2Se-Cl-m,regiorandom PY2Se-Cl-ran has a similar absorption profile,moderate lowest unoccupied molecular orbital level,and favorable intermolecular packing and crystallization properties.Moreover,the binary PM6:PY2Se-Cl-ran blend achieves better ductility with a crack-onset strain of 17.5% and improved power conversion efficiency(PCE)of 16.23% in all-polymer solar cells(all-PSCs)due to the higher molecular weight of PY2Se-Cl-ran and optimized blend morphology,while the ternary PM6:J71:PY2Se-Cl-ran blend offers an impressive PCE approaching 17% and excellent device stability,which are all crucial for potential practical applications of all-PSCs in wearable electronics.To date,the efficiency of 16.86% is the highest value reported for the regiorandom PSMAs-based all-PSCs and is also one of the best values reported for the all-PSCs.Our work provides a new perspective to develop efficient all-PSCs,with all high active layer ductility,impressive PCE,and excellent device stability,towards practical applications. | Qunping Fan Ruijie Ma Wenyan Su Qinglian Zhu Zhenghui Luo Kai Chen Yabing Tang Francis RLin Yuxiang Li He Yan Chuluo Yang Alex K.-Y.Jen Wei Ma | 2023 | Carbon Energy2023，5，2： | 0 |
| 15 | Multiple Resonance Thermally Activated Delayed Fluorescence Sensitizers Enable Green-toUltraviolet Photon Upconversion:Application in Photochemical Transformations显示文摘Efficient visible-to-ultraviolet(UV)triplet-triplet annihilation upconversion(TTA-UC)with large anti-Stokes shift is highly promising for solar-powered and indoor applications.Nonetheless,the excitationwavelengthis confined to the blue region(<450 nm),mainly due to large energy loss during triplet sensitization,resulting in reduced photon utilization efficiency in practical scenarios.Herein,a series of multiple resonance thermally activated delayed fluorescence(MR-TADF)compounds are developed as purely organic sensitizers for the purpose of energy-loss reduction,which also feature intense absorbance in the visible region,high intersystem crossing efficiencies,and long triplet lifetimes.By pairing the MR-TADF sensitizers with appropriate acceptors,green-to-UV TTA-UC systems were realized with an anti-Stokes shift up to 1.05 eV,upconversion quantum yield up to 8.6%,and threshold excitation intensity as low as 9.2 mW cm^(−2) in solution.The TTA-UC pairs were applied as internal or external sources of UV photons to trigger energy-demanding photopolymerization and photoligation reactions even under excitation of low-power-density green light-emitting diode light,revealing the broad utility of thesemolecular upconverters.This work unlocks the huge potential of MR-TADF-type sensitizers in upconversion applications. | Yaxiong Wei Ke Pan Xiaosong Cao Yuanming Li Xiaoguo Zhou Chuluo Yang | 2022 | CCS Chemistry2022，4，12： | 0 |
| 16 | Multifunctional all-polymer photovoltaic blend with simultaneously improved efficiency(18.04%),stability and mechanical durability显示文摘One of the most appealing material systems for solar energy conversion is allpolymer blend.Presently,the three key merits(power conversion efficiency,operation stability and mechanical robustness)exhibited a trade-off in a particular all-polymer blend system,which greatly limit its commercial application.Diverting the classic ternary tactic of organic solar cells based on polymer,nonfullerene small molecule and fullerene,herein we demonstrate that the three merits of a benchmark all-polymer blend PM6:PY-IT can be simultaneously maximized via the introduction of a polymerized fullerene derivative PPCBMB.Importantly,the addition of the guest component promoted the power conversion efficiency of PM6:PY-IT blend from 16.59%to 18.04%.Meanwhile,the device stability and film ductility are also improved due to the addition of this polymerized fullerene material.Morphology and device physics analyses reveal that optimal ternary system contains well-maintained molecular packing and crystallinity,being beneficial to keeping favorable charge transport and the reduced domain size contributed to charge generation and ductility improvement.Furthermore,the ternary photovoltaic blend was successfully used as photocatalysts,and an excellent heavy metal removal from water was demonstrated.This study showcases the multi-functions of all-polymer blends via the use of polymerized fullerenes. | Tao Liu Kangkang Zhou Ruijie Ma Libin Zhang Ciyuan Huang Zhenghui Luo Hongxiang Zhu Shangfei Yao Chuluo Yang Bingsuo Zou Long Ye | 2023 | Aggregate2023，4，3： | 0 |
| 17 | Step‑by‑Step Modulation of Crystalline Features and Exciton Kinetics for 19.2%Efficiency Ortho‑Xylene Processed Organic Solar Cells显示文摘With plenty of popular and effective ternary organic solar cells(OSCs)construction strategies proposed and applied,its power conversion efficiencies(PCEs)have come to a new level of over 19%in single-junction devices.However,previous studies are heavily based in chloroform(CF)leaving behind substantial knowledge deficiencies in understanding the influence of solvent choice when introducing a third component.Herein,we present a case where a newly designed asymmetric small molecular acceptor using fluoro-methoxylated end-group modification strategy,named BTP-BO-3FO with enlarged bandgap,brings different morphological evolution and performance improvement effect on host system PM6:BTP-eC9,processed by CF and ortho-xylene(o-XY).With detailed analyses supported by a series of experiments,the best PCE of 19.24%for green solvent-processed OSCs is found to be a fruit of finely tuned crystalline ordering and general aggregation motif,which furthermore nourishes a favorable charge generation and recombination behavior.Likewise,over 19%PCE can be achieved by replacing spin-coating with blade coating for active layer deposition.This work focuses on understanding the commonly met yet frequently ignored issues when building ternary blends to demonstrate cutting-edge device performance,hence,will be instructive to other ternary OSC works in the future. | Bosen Zou Weiwei Wu Top Archie Dela Pena Ruijie Ma Yongmin Luo Yulong Hai Xiyun Xie Mingjie Li Zhenghui Luo Jiaying Wu Chuluo Yang Gang Li He Yan | 2024 | Nano-Micro Letters2024，16，2： | 0 |
| 18 | Luminescent gold(Ⅲ)exciplexes enable efficient multicolor electroluminescence显示文摘The control of excited states and related emissive properties of gold(Ⅲ)complexes mainly depends on the modulation of intramolecular electronic interactions among gold(Ⅲ)metal center,chelating ligands and/or peripheral groups.However,luminescent gold(Ⅲ)systems based on intermolecular electronic interactions have never been explored.Here we report a series of proof-of-concept gold(Ⅲ)exciplexes using a simple gold(Ⅲ)complex,AuDPPy,as an electron acceptor.The emissive properties of gold(Ⅲ)exciplexes can be regulated by combining AuDPPy with different donors.Inspiringly,these gold(Ⅲ)exciplexes have donor-dependent emission mechanisms:dominant phosphorescence or dual radiative channels of thermally activated delayed fluorescence(TADF)and phosphorescence.Consequently,these gold(Ⅲ)exciplexes deliver green-to-red electroluminescence with external quantum efficiencies(EQEs)of up to 10.1%.More importantly,using these gold(Ⅲ)exciplexes to host multi-resonance TADF emitters results in narrowband yellow,orange,and deep-red electroluminescence with high EQEs of 23.5%,24.4%,and 27.4%,respectively,competitive to the highest values for gold(Ⅲ)OLEDs in similar color gamut. | Lisi Zhan Tianhao Chen Cheng Zhong Xiaosong Cao Yuewei Zhang Yang Zou Zhengyang Bin Jingsong You Dongdong Zhang Lian Duan Chuluo Yang Shaolong Gong | 2023 | Science China Chemistry2023，66，11： | 0 |
| 19 | Tetradentate cyclometalated platinum complex enables high-performance near-infrared electroluminescence with excellent device stability显示文摘Due to the high decay rate of the non-radiative transition of long wavelengths, the molecular design of efficient and stable near-infrared(NIR) electroluminescent materials remains a big challenge. Herein,a new tetradentate cyclometalated platinum(II) complex with an N∧C∧C∧N coordinated framework has been developed and used as a dopant for NIR organic light-emitting diodes(OLEDs). The complex exhibited a short-lived(0.5–1.5 μs) metal-to-ligand charge transfer(MLCT) excited state in doped and neat films. The resulting NIR OLEDs(λ_(EL)= 730 nm) achieved maximum external quantum efficiency(EQE_(max))of 5.2% and radiance of 74626 m W sr^(-1)m^(–2). Of note, the device exhibited excellent stability with operational lifetime of 119 h for LT_(90). This work demonstrated the great potential of tetradentate platinum(II)complexes in the field of NIR OLEDs. | Chengjun Wu Youming Zhang Jingsheng Miao Kai Li Weiguo Zhu Chuluo Yang | 2023 | Chinese Chemical Letters2023，34，2： | 0 |
| 20 | Heteroheptacene-based acceptors with thieno[3,2-b]pyrrole yield high-performance polymer solar cells显示文摘Rationally utilizing and developing synthetic units is of particular significance for the design of high-performance non-fullerene small-molecule acceptors(SMAs).Here,a thieno[3,2-b]pyrrole synthetic unit was employed to develop a set of SMAs(ThPy1,ThPy2,ThPy3 and ThPy4)by changing the number or the position of the pyrrole ring in the central core based on a standard SMA of IT-4Cl,compared to which the four thieno[3,2-b]pyrrole-based acceptors exhibit bathochromic absorption and upshifted frontier orbital energy level due to the strong electron-donating ability of pyrrole.As a result,the polymer solar cells(PSCs)of the four thieno[3,2-b]pyrrole-based acceptors yield higher open-circuit voltage and lower energy loss relative to those of the IT-4Cl-based device.What is more,the ThPy3-based device achieves a power conversion efficiency(PCE)(15.3%)and an outstanding fill factor(FF)(0.771)that are superior to the IT-4Cl-based device(PCE=12.6%,FF=0.758).The ThPy4-based device realizes the lowest energy loss and the smallest optical band gap,and the ternary PSC device based on PM6:BTP-eC9:ThPy4 exhibits a PCE of 18.43%and a FF of 0.802.Overall,this work sheds light on the great potential of thieno[3,2-b]pyrrole-based SMAs in realizing low energy loss and high PCE. | Zhenghui Luo Ruijie Ma Jianwei Yu Heng Liu Tao Liu Fan Ni Jiahao Hu Yang Zou Anping Zeng Chun-Jen Su U-Ser Jeng Xinhui Lu Feng Gao Chuluo Yang He Yan | 2022 | National Science Review2022，9，7： | 0 |
