| 2 | Benzothiophene and benzosulfone fused pyrazino[2,3-g]quinoxaline:Synthesis and semiconducting properties显示文摘A novel air-stable n-type benzothiaphene endcapped azaarene(BTPQ) and its sulfonated derivative(BSPQ) were prepared via two pathways and characterized by NMR, UV–vis, fluorescence and cyclic voltammetry spectroscopy. Symmetrically introducing four nitrogen atoms into acenes, the semiconductor properties could be changed from p-type to n-type detected through the space charge limited current(SCLC) method. After sulfonation of BTPQ, BSPQ is with deeper frontier orbital energy levels and enhanced the electron mobility. | Fangwei Ding Debin Xia Xiping Ding Ruibin Deng Congwu Ge Yulin Yang Ruiqing Fan Kaifeng Lin Xike Gao | 2023 | Chinese Chemical Letters2023，34，2： | 0 |
| 3 | Alkali metal cation engineering in organic/inorganic hybrid perovskite solar cells显示文摘The past decade has witnessed the rapid advance in organic–inorganic hybrid perovskite solar cells(PSCs).Owing to unique optoelectronic properties of perovskites,the power conversion efficiency(PCE)of PSCs has jumped from 3.8%to25.5%[1–4].However,under the stimulus of illumination,moisture,oxygen and heat,perovskites exhibit unsatisfactory stability due to weak bonding among the components in these soft-lattice crystals[5–7].Doping and passivation engineering with alkali metal cations can enhance the intrinsic stability of perovskite materials.Here,the recent progress of alkali metal cations engineering is reviewed,and the impact on the crystallization,lattice structure,photovoltaic performance and stability is discussed. | Jilin Wang Ruibin Tang Lixiu Zhang Fei Long Disheng Yao Liming Ding | 2022 | Journal of Semiconductors2022，43，1： | 0 |
| 4 | Interannual variations in salt flux at 80°E section of the equatorial Indian Ocean显示文摘The interannual variations in salt flux on the 80°E section in the equatorial Indian Ocean were explored based on the ORAS5 data,which was quite consistent with the observational data among the four available reanalysis datasets.The results indicated that the area with significant interannual variations in salt flux coincided with that of significant climatological mean salt flux in general and was mainly located in the upper 150 m layer.Specifically,three important areas were identified in the north-south direction,i.e.,(1)the Equatorial Indian Ocean Area(EIOA,3°S–3°N),where the mean salt flux was eastward with the largest value on the section and associated with the most significant interannual variations mainly modulated by the Wyrtki Jets and the Equatorial Undercurrent;(2)the South Equatorial Indian Ocean Area(SEIOA,3°S–6°S),where the mean salt flux changed in the vertical direction from strong eastward flux in the upper layer to weak westward flux in the subsurface layer and associated with significant interannual variations in the upper 100 m layer,which was affected by the South Equatorial Countercurrent;and(3)the North Equatorial Indian Ocean Area(NEIOA,3°N–6°N),where the mean salt flux changed in the north-south direction from strong westward flux to the north of 5°N to weak eastward flux in the south and associated with relatively significant interannual variations,which was mainly influenced by the South Sri Lanka Coastal Current.Two leading interannual variation modes were revealed by the empirical orthogonal function decomposition.The first mode accounted for 39%of the total variance and had four significant spatial antinodes;two of those in-phase antinodes were located at SEIOA and upper 75 m of EIOA,and the other two opposite in-phase antinodes were located at NEIOA and below 75 m of EIOA.The second mode accounted for 17%of the total variance having four antinodes with two dominant out-of-phase antinodes located at the subsurface of EIOA and SEIOA.The temporal components of the two leading modes showed a 1–4 year variation with a main period of 2 years,in which the first mode showed a greater correlation with the Indian Ocean Dipole,while the second mode showed a weak correlation with the Indian Ocean Dipole and the El Niño-Southern Oscillation.Variance analysis showed that the interannual variations in salt flux were mainly determined by the variations in the current,and the spatial distribution was modulated by temporal mean salinity.Composite strong interannual events showed interannual variations in current,and so the salt flux was driven by the interannual anomaly of the wind field and sea surface temperature associated with the Indian Ocean Dipole. | Cuncun XIE Ruibin DING Jiliang XUAN Daji HUANG | 2023 | Science China Earth Sciences2023，66，9： | 0 |
| 5 | Three-primary-color molecular cocrystals showing white-light luminescence,tunable optical waveguide and ultrahigh polarized emission显示文摘Three-primary-color luminescent materials are highly desirable to construct white-light emitting resource,multi-color optical displays,and tunable photonic applications.However,the efficient strategy to establish the three-primary-color systems with unique photofunctionalities is still rather limited,particularly for molecular materials.Herein,we developed a molecular cocrystal route to obtain three-primary-color emissive materials by tuning different donor-acceptor units based on the same chromophore(4,4′-bis(2,5-dimethylstyryl)biphenyl,Bdb).The warm and cold white-light together with multi-color emission in most of visible region can be highly adjusted by rationally tuning different mixture components of three-primary-color cocrystals through an energy transfer mechanism.Furthermore,the blue/green/red emitters endow Bdb molecular cocrystals novel colortunable photonic properties(such as one-dimensional(1D)/2D optical waveguide,polarized fluorescence,up-conversion luminescence,and amplified spontaneous emission),benefitting from their well-defined micro/nanostructures and high crystallinity.Particularly,the high luminescence quantum yield(82.49%)and polarized anisotropy(0.723)outperform most of state-ofthe-art molecular crystalline materials.Therefore,this work supplies an effective way to fabricate new types of three-primarycolor phosphors through luminescent cocrystals,which have promising applications in the fields of full-color displays,whitelight irradiation,low-dimensional optical polarization,and micro/nanophotonics. | Shuzhen Li Yan Hao Shuai Guo Chunjie Ding Yujuan Ma Ruibin Liu Dongpeng Yan | 2022 | Science China Chemistry2022，65，2： | 0 |
