Multifunctional organic fluorescent materials derived from 9,10-distyrylanthracene with alkoxyl endgroups of various lengths

A series of remarkable multifunctional 9,10-distyrylanthracene derivatives (DSA(n), n = 7-12) was synthesized. All derivatives possess typical aggregation-induced emission (AIE) property. Some of the derivatives exhibit multifunctional properties, including AIE, mechanofluorochromism, vapochromism, thermochromism, and mesomorphism, which are rarely found to exist simultaneously in a single compound.
