| 1 | A Nonlinear Optical Switchable Sulfate of Ultrawide Bandgap显示文摘Nonlinear optical(NLO)switchable materials have attracted intense attention because of their promising applications in optoelectronic devices.However,previous studies are mainly limited to molecular-based compounds that usually exhibit narrow bandgaps.Here,we report all-inorganic Li_(9)Na_(3)Rb_(2)(SO_(4))_(7) as an ultrawide-bandgap NLO switchable material. | Yanqiang Li Congling Yin Xiaoyan Yang Xiaojun Kuang Jie Chen Lunhua He Qingran Ding Sangen Zhao Maochun Hong Junhua Luo | 2021 | CCS Chemistry2021，3，7： | 1 |
| 2 | Nonpolar Na_(10)Cd(NO_(3))_(4)(SO_(3)S)_(4) Exhibits a Large Second-Harmonic Generation显示文摘Conventional wisdom says that nonpolar structures do not favorably produce strong second-harmonic generation(SHG)responses since the polarization in their microscopic functional groups are counteracted.Herein,we report the first nonlinear optical thiosulfate,Na_(10)Cd(NO_(3))_(4)(SO_(3)S)_(4),which crystallizes in a nonpolar space group of P−4.However,this thiosulfate exhibits a strong SHG response of about 4.2 times that of the benchmark KH2PO4,which is larger than those of polar sulfates.According to first-principles calculations and a flexible dipole model,the SHG enhancement is mainly ascribed to the larger flexibility of the S=S bond in the SO_(3)S tetrahedra in comparison with the S–O bond in the SO4 tetrahedra.These findings indicate that constructing flexible bonds is an effective strategy to design highperformance nonlinear optical materials regardless of polarity. | Youchao Liu Youquan Liu Zheshuai Lin Yanqiang Li Qingran Ding Xin Chen Lina Li Sangen Zhao Maochun Hong Junhua Luo | 2022 | CCS Chemistry2022，4，2： | 1 |
| 3 | Evaluation of the predominant bacteria and proinflammatory cytokine expressions in odontogenic cysts显示文摘Odontogenic cysts(ODCs)originated from odontogenic epithelium are the most common cyst that may exhibit local destructive behavior.Radicular cysts(RCs)and developmental odontogenic ker-atocysts(OKCs)are the two most commonly encountered types in practice.Infection of necrotic teeth is responsible for the formation of RCs and progresses as apical lesions,whereas OKCs react with an inflammatory response to chronic irritation caused by necrotic teeth[1]. | Yan Li Qingran Yang Chi Yang Kan Ding Guangzhou Xu | 2022 | Acta Biochimica et Biophysica Sinica2022，54，3： | 0 |
| 4 | Noncentrosymmetric K_(2)Mn_(3)(SO_(4))_(3)F_(2)·4H_(2)O and Rb_(2)Mn_(3)(SO_(4))_(3)F_(2)·2H_(2)O with pseudo-KTP structures显示文摘Two fluoride sulfates,K_(2)Mn_(3)(SO_(4))_(3)F_(2)·4H_(2)O(Ⅰ) and Rb_(2)Mn_(3)(SO_(4))_(3)F_(2)·2H_(2)O (Ⅱ) are obtained by water solution method.Single-crystal X-ray diffraction analysis indicated that they crystallize in space groups of Cmc2_(1.)Their structures feature a pseudo-KTP structure consisting of interconnecting[Mn_(3)(SO_(4))3F_(2)(H_(2)O)2]_(∞) layers,which are further packing along the a axis with alkali metal cations balancing the charges.The structure relationships between the two compounds are discussed.Secondharmonic generation measurements manifest that Ⅰ and Ⅱ have similar second-harmonic generation responses of about 0.2 and 0.25 times that of KH_(2)PO_(4). | Yang Zhou Yanqiang Li Qingran Ding Youchao Liu Yangxin Chen Xitao Liu Xiaoying Huang Lina Li Sangen Zhao Junhua Luo | 2021 | Chinese Chemical Letters2021，32，1： | 0 |
| 5 | Designing a deep-UV nonlinear optical monofluorophosphate显示文摘As structural variants of famous hexagonal tungsten bronzes,hexagonal tungsten oxides(HTO)represent an important family with fascinating functional properties,such as piezoelectric,ferroelectric,pyroelectric,and nonlinear optical(NLO)properties.However,none of them are transparent in the deep-UV spectral region,which limits their applications.Herein,we report the first HTO-type monofluorophosphate K_(3)Sc_(3)(PO_(4))(PO_(3)F)_(2)F_(5)(I)with deep-UV transparency.Such a monofluorophosphate is NLO-active with a phase-matchable powder second harmonic generation efficiency of 0.9 times that of KH_(2)PO_(4)at 1,064 nm.Importantly,the UV-Vis reflectance spectrum indicates that it is deep-UV transparent down to 200 nm.This work pushes the transparent window of NLO materials with HTO-type structures down to the deep-UV spectral region for the first time and opens up a new door for HTO materials. | Qingran Ding Xingyu Zhang Zheshuai Lin Zheyao Xiong Yusong Wang Xifa Long Sangen Zhao Maochun Hong Junhua Luo | 2022 | Science China Chemistry2022，65，9： | 0 |
