Novel indoloquinoxaline-tetraphenylethylene star-like conjugated isomers: aggregation-induced emission and acidichromism for versatile fluorescent applications

A pair of star-like conjugated isomers (Tetra-8-IQ and Tetra-9-IQ) with indolo[2,3- b ]quinoxaline as the star arm and tetraphenylethylene as the star core have been designed and synthesized.
