Journal ArticleDOI
Versatile Room-Temperature-Phosphorescent Materials Prepared from N-Substituted Naphthalimides: Emission Enhancement and Chemical Conjugation.
Xiaofeng Chen,Cheng Xu,Tao Wang,Zhou Cao,Jiajun Du,Zhongping Wang,Hangxun Xu,Tongqing Xie,Guo-Qiang Bi,Jun Jiang,Xuepeng Zhang,James N. Demas,Carl Trindle,Yi Luo,Guoqing Zhang +14 more
TL;DR: It is shown that donor-to-acceptor CT states from the same organic molecule can also mediate π-localized RTP, inspired by certain organometallic systems.
Journal ArticleDOI
Designing Efficient and Ultralong Pure Organic Room-Temperature Phosphorescent Materials by Structural Isomerism.
Yu Xiong,Zheng Zhao,Weijun Zhao,Huili Ma,Qian Peng,Zikai He,Xuepeng Zhang,Yuncong Chen,Xuewen He,Jacky Wing Yip Lam,Ben Zhong Tang,Ben Zhong Tang +11 more
TL;DR: Study of the structure-property relationship shows that the varied steric and conjugation effects imposed by ester substituent at different positions are responsible for the small ΔEST and pure ππ* configuration of T1 .
Journal ArticleDOI
Ultralong UV/mechano-excited room temperature phosphorescence from purely organic cluster excitons.
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
Boosting the efficiency of organic persistent room-temperature phosphorescence by intramolecular triplet-triplet energy transfer.
Weijun Zhao,Tsz Shing Cheung,Nan Jiang,Wenbin Huang,Jacky W. Y. Lam,Xuepeng Zhang,Zikai He,Ben Zhong Tang,Ben Zhong Tang +8 more
TL;DR: The strategy developed here will enable the development of efficient phosphorescent materials for potential high-tech applications and enhance persistent room-temperature phosphorescence efficiency via intramolecular triplet-triplet energy transfer.
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.
