Abstract

The invention relates to a preparation method for constructing a two-dimensional ultra-long room-temperature phosphorescent material based on cation-pi action driving. The method is characterized in that a 2,4,6-tri(9H-carbazole-9-yl)-1,3,5-triazine monomer is a B3 monomer containing three degrees of functionality, commercial 2', 4', 5', 7'-tetrabromo-4, 5, 6, 7-tetrachloro-3', 6'-dihydroxy-spiro [isobenzofuran-1(3H),9'-(9H) xanthene]-3-one is an A2 monomer containing two sodium ions, the carbazole part of the 2,4,6-tri(9H-carbazole-9-yl)-1,3,5-triazine and the sodium cation of 2', 4', 5', 7'-tetrabromo-4, 5, 6, 7-tetrachloro-3', 6'-dihydroxy-spiro [isobenzofuran-1(3H),9'-(9H) xanthene]-3-one are assembled by using the two monomers through a grinding assembly method under the driving of cation-pi supramolecular force, so that a supramolecular two-dimensional material with high strength, good stability and ultra-long room-temperature phosphorescence emission is obtained, wherein the material has great application prospects in the aspects of multiple anti-counterfeiting, encryption, conductive materials, flexible electronic materials, self-repairing materials and the like.
