AIE-Active Mechanoluminescent Discotic Liquid Crystals for Applications in OLEDs and Bio-Imaging

Abstract

A multifunctional molecular design of fluorescent discotic liquid crystal (DLC) consisting of tetraphenylethylene core is reported which is found to serve as an excellent solid-state emitter in OLED devices with EQE of 4.4% and tunable mechanochromism. X-ray diffraction studies unveiled that change in supramolecular self-assembly is the physical origin of mechanochromism. The luminescent DLC molecule has been shown to act as a highly selective probe for labelling acidic cellular compartments (such as lysosomes) in bio-imaging using HeLa cells.
