Xuepeng Zhang,Lili Du,Weijun Zhao,Zheng Zhao,Yu Xiong,Xuewen He,Peng Fei Gao,Parvej Alam,Can Wang,Zhen Li,Jing Leng,Junxue Liu,Chuanyao Zhou,Jacky W. Y. Lam,David Lee Phillips,Guoqing Zhang,Ben Zhong Tang,Ben Zhong Tang +17 more
TL;DR: By dissolving 1,8-naphthalic anhydride in certain organic solid hosts, URTP with a lifetime of over 600 ms and overall quantum yield of over 20% is realized and is expected to help expand the varieties of purely organic URTP materials based on an advanced understanding of guest/host combinations.
Journal ArticleDOI
Two Are Better Than One: A Design Principle for Ultralong-Persistent Luminescence of Pure Organics.
Parvej Alam,Nelson L. C. Leung,Junkai Liu,Tsz Shing Cheung,Xuepeng Zhang,Zikai He,Ryan T. K. Kwok,Jacky W. Y. Lam,Herman H. Y. Sung,Ian D. Williams,Christopher C. S. Chan,Kam Sing Wong,Qian Peng,Ben Zhong Tang,Ben Zhong Tang +14 more
TL;DR: A design principle based on the successes of inorganic systems to produce an organic LPL (OLPL) system through the use of a strong organic electron trap is proposed, and the resulting system generates detectable afterglow for up to 7 h, significantly longer than any other reported OLPL system.
Journal ArticleDOI
Stimuli-Responsive AIEgens
TL;DR: In this article, the recent achievements of stimuli-responsive AIEgens in terms of seven most representative types of stimuli including force, light, polarity, temperature, electricity, ion, and pH are summarized.
Journal ArticleDOI
AIE-based luminescence probes for metal ion detection
Parvej Alam,Nelson L. C. Leung,Jing Zhang,Ryan T. K. Kwok,Jacky Wing Yip Lam,Ben Zhong Tang,Ben Zhong Tang +6 more
TL;DR: An overview of the design principles of metal ion responsive AIEgens that can be generated using a modular approach can be found in this paper, where the authors have summarized the typical examples and their sensing mechanisms developed from 2005 to 2020.
Journal ArticleDOI
A multi-stimuli responsive “AIE” active salicylaldehyde-based Schiff base for sensitive detection of fluoride
TL;DR: In this article, a Schiff-base compound was synthesized and the investigation of solid state emission property was carried out and the observed bright emission in solid state was identified it as an aggregation induced emission (AIE) active compound.
