Progress in the study of hydrogen-bonded organic frameworks based on tetraphenylethylene luminescent core
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.
