Abstract

The time-resolved photophysical analysis of a multi-color-changing mechanochromic luminescent compound has been disclosed, which reveals distinct different emission paths to boost TADF and RTP of the emitter depending on its molecular conformations. Furthermore, by making use of the obtained knowledge here, we also present the possibility to control the emission colors by regulating the population of conformers formed inside the emissive layer by solution processing, and this technique was applied to fabricate the emissive layers of OLED devices.
