Convenient construction of tetraphenylethene (TPE) derivatives through Cu(ii) mediated cascade dehydrogenation of EWG-activated diphenylmethane

Abstract

Tetraphenylethene (TPE) is a prototypical structural motif frequently found to be incorporated into the material related to aggregation-induced emission (AIE), covalent-organic framework (COF), molecular cage et al., and often synthesized...
