The invention discloses a
phosphorescence aggregation-induced emission material of a
platinum (II) complex containing a
nitrogen monodentate ligand and a C^N bidentate ligand. According to the invention, a planar
platinum (II) complex is used as a framework to design and synthesize a Pt (C^N)NCl type phosphorescent AIE molecule, C^N is a 2-phenylpyridine bidentate ligand, N is a
nitrogen-containing monodentate ligand, and Cl is a
chlorine monodentate ligand. On the basis, the
phosphorescence AIE behavior is regulated and controlled by regulating and controlling the sizes of a C^N bidentate ligand and a
nitrogen-containing monodentate ligand, and the new
phosphorescence AIE characteristic is realized by utilizing the conversion blocking of a tetrahedral framework from a
ground state plane coordination framework to an
excited state in an aggregation state, besides, through the intermolecular action, the rotation of groups on the ligand is hindered, and the nonradiative attenuation of theexcited state of the phosphorescent complex can also be inhibited to increase the aggregation-state light-emitting capacity, so that the realization of the AIE property is achieved, and the
functional modification is performed on the two ligands, so that the space for regulating and controlling the AIE performance of the
platinum (II) complex is remarkably improved.
