Mol. 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 nematic (CS1-6) or smectic C (CS1-12) phase with different alkyl tail lengths. When the single aliphatic chain is replaced by mini-dendrons, room temperature (RT) monotropic hexagonal columnar phase (CS2-12) or mol. liquid (CS2-6) is formed. The results revealed that all these materials exhibited high efficiency emission with the highest quantum yield reaching 59.0%. The photoluminescence and photothermal effect can be effectively tuned by dispersing CSs into a com. available RT liquid crystal matrix 8CB, which output significantly improved photothermal conversion efficiency of 63.2%. Furthermore, the photothermal can rapidly trigger the Smectic A-Nematic-Isotropic sequence transitions of 8CB doped with CSs. This work paves a way of adjusting the balance of photoluminescence and photothermal properties of the LLC materials.
