摘要： 具有精细结构的1DmCZ分子基于咔唑基团本身具有良好给体材料的基础上，引入-CN基团作为受体，从而合成出具有扭曲结构的双D=A结构分子，实现了长余辉长寿命室温磷光材料的合成。通过溶剂挥发方法培养出单晶结构，并对其独特结构进行解析，最终得出其独特的扭曲结构和强大的分子间相互作用力是分子产生长寿命磷光余辉的根本原因。

Abstract: The 1DmCZ molecule with fine structure is based on the good donor material of thecarbazole group itself, and the -CN group is introduced as the acceptor, so as to synthesize a double D=A structure molecule with a twisted structure, and realize the synthesis of long-afterglow and long-lived room-temperature phosphorescent materials. In this paper, the single crystal structure was cultivated by solvent volatilization method, and its unique structure was analyzed, and finally it was concluded that its unique twisted structure and strong intermolecular interaction force were the fundamental reasons for the long-lived phosphorescent afterglow of the molecule.
Key words: room temperature phosphorescence; D-A structure; phosphorescent lifetime
