The invention provides a diamine compound containing three N centers, a preparation method and application thereof, a polyamide and the preparation and application thereof, belonging to the technical field of optoelectronic materials. The diamine compound of the present invention contains three N-atom electroactive centers and a high-efficiency fluorophore R, and the three N atoms can not only impart multiple electrochromic behaviors to the polymer prepared from the diamine compound, but also form a structure with the benzene ring. The resulting bis-p-phenylenediamine structure can also effectively stabilize cationic radicals. N,N-dimethyl is not only the third N atom center provider, but also acts as a strong electron donating group, which can effectively reduce the oxidation potential of the polymer. , so that the polymer has good electrochemical stability. The synergistic effect of high-efficiency fluorophore and propeller-type triphenylamine construction can make the polymer have high fluorescence contrast, and at the same time improve the stacking mode of the polymer, so that the polymer has good solubility while maintaining its own inherent thermal stability. |
