Twisted D–π–A solid emitters: efficient emission and high contrast mechanochromism

Abstract

Triphenylacrylonitrile and diarylamine based D–π–A luminogens exhibit typical AIE characteristics with high solid state efficiency up to unity and switchable mechanochromism with high contrast, which render them multifunctional materials for versatile applications in optical storage, volatile organic compound (VOC) detection, OLEDs, etc.
