Abstract

Schiff base condensation and C–C coupling between a biologically important heterocycle pyrido[1,2-a]indole (PI) and aggregation induced emission active tetraphenylethylene (TE) led to the formation of weakly fluorescent PITE1 and strongly fluorescent PITE2, respectively. The photophysical phenomenon was rationalized by crystal structure analysis; PITE2 was found to exhibit strong fluorescence in solution, nanoparticles and solid state.
