摘要
氢键有机框架(HOF)在化学传感、主客体组装、催化反应、加密防伪、刺激发光响应、气体吸附分离等领域具有重大的应用前景,是目前研究的热点之一.把聚集诱导发光(AIE)核心基元四苯乙烯(TPE)引入到HOF构筑单元的分子结构中,可以综合AIE核心基团高效的固体发光性能和构象易旋转的介稳性能,同时HOF多孔结构又赋予它许多特别的性能,是一类有重要研究价值和应用前景的HOF材料.本文综述了基于四苯乙烯发光核的氢键有机框架国内外研究进展情况,并重点介绍了本课题组在这方面的研究进展.
Abstract
Hydrogen-bonded organic framework(HOF)has great potential applications in chemical sensing,host-guest assembly,catalytic reaction,encryption and anti-counterfeiting,stimuli-responsive luminescence,gas adsorption and separation,etc.,and is one of the hot topics of current researches.Tetraphenylethylene(TPE),as one of aggregation-induced emission(AIE)core groups,has been introduced into the molecular structure of HOF building units,which can combine the high-efficient solid-state luminescence property and metastable property of the conformational rotation of the AIE core,and the porous structure of HOF which gives it many special properties.The HOFs based on TPE is a kind of HOF materials with important research value and application prospect.In this paper,the progress in the research of HOF based on TPE is reviewed.
