Suppression of reversible photocyclization reaction induced fluorescence enhancement: a theoretical study
Autor: Haoran Wei, Yi Zeng, Quansong Li, Xiaoyan Zheng
Publikováno v: Physical chemistry chemical physics : PCCP. 24(41)
Aggregation-induced emission (AIE) materials with photocyclization (PC) reactions exhibit rich photophysical and photochemical activities. Understanding the mechanism behind is essential to the design of effective AIE materials. Herein, we employ a p

Theoretical Study on Photoisomerization Mechanisms of Diphenyl‐Substituted N,C‐Chelate Organoboron Compounds
Autor: Xin-Yi Du, Quansong Li
Publikováno v: Chemistry – A European Journal. 26:12891-12897
N,C-chelate organoboron compounds are widely employed as photoresponsive and optoelectronic materials due to their efficient photochromic reactivity. It was found in experiments that two diphenyl-substituted organoboron compounds, namely B(ppy)Ph2 (p

Unexpected synthesis and structure of a cage-like aza[3,3,3]propllane carbene
Autor: Qi Zhang, Jiarong Li, Guangwei Zhou, Su Ziqi, Quansong Li, Chen Qianzhu, Yahan Xue, Qunsheng Yan, Lizhu Zhang, Juan Xu
A stable, propeller-like N-heterocyclic cage carbene with a protective umbrella was unexpectedly synthesized in the hydrogen proton transfer catalytic hydrogenolysis. Its structural and spectral characteristics are obviously different from those of c

A new method to optimize the azimuth angle of elements in a projection lens
Autor: Zhao Yang, Hongbo Shang, Chunlai Liu, Wang Ping, Quansong Li, Shudong Men
Publikováno v: Optics Communications. 381:365-370
In the manufacturing process of high-precision photolithography lens, clocking of lens element is a commonly used and efficient method to compensate the surface figure error. This method obtains the optimal azimuth angles of a lens element. With comp

Restricted access to a conical intersection to explain aggregation induced emission in dimethyl tetraphenylsilole
Autor: Lluís Blancafort, Sergi Ruiz-Barragan, Quansong Li, Xing-Liang Peng, Ze-Sheng Li
Publikováno v: Journal of Materials Chemistry C. 4:2802-2810
The mechanism behind aggregation induced emission (AIE) in the prototypical dimethyl tetraphenylsilole (DMTPS) molecule is investigated with ab initio calculations combining the CASSCF and CASPT2 methods with time-dependent DFT. DMTPS is AIE-active b
