Luminescent materials possessing a “hot‐exciton” mechanism and aggregation‐induced emission (AIE) qualities are well‐suited for use as emitting materials in nondoped organic light‐emitting diodes (OLEDs), particularly in deep‐red regions where their ground state and singlet excited state surfaces are in proximity, leading to the formation of multiple nonradiative channels. However, designing molecules...
Molecular motions of the luminescent liquid crystals (LLCs) show a significant effect on fluorescent emission and heat generation. In this article, a series of cyanostilbene‐based LLCs (CSs: CS1‐6, CS1‐12, CS2‐6 and CS2‐12) are synthesized to investigate how the photoluminescence and photothermal effect balanced. Among these materials, the mesogens peripheried by single alkyl chains formed enantiotropic...
