Study on the Phosphorescent Properties of Small Molecules in Long-lived Crystalline States
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 synthe-size 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 struc-ture 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 phosphores-cent afterglow of the molecule.
