Luminescent discotic liquid crystals ： from molecular design to applications

Abstract：Luminescent discotic liquid crystals（L-DLCs）are advanced functional materials that exhibit remarkable characteristics in both molecular structure and luminescent properties. This review provides a comprehensive overview of the molecular design，performance modulation，and applications of L-DLCs. First，the basic concept，typical molecular structure，and liquid crystalline phases of these materials are introduced.The review then discusses in detail the excellent performance ofL-DLCs in both fluorescence and phosphorescence mechanisms，with molecular design strategies enabling light emission across different wavelength ranges. Next， the applications of L-DLCs in organic electronic devices are highlighted. Finally，the currnt state and future trends in this field are summarized，with a focus on molecular structure optimization，improvements in fabrication processes，and the development of device integration strategies，aiming to enhance the overall performance of L-DLCs and accelerate their practical applications
