Diamine compound and its preparation method and application

The invention discloses a novel diamine compound, and a preparation method and an application thereof. The preparation method of the novel functional diamine compound comprises the following steps: a large conjugate structure comprising benzophenone carbonyl group is obtained; the ketone carbonyl group is subjected to a Wittig or Wittig-Horner reaction, such that a large conjugate system with a triphenylethylene/tetraphenylethylene structure and comprising a halogen atom is obtained; the halogen atom is further subjected to a Suzuki reaction or a plurality steps of reactions, such that a monoamine compound comprising a triphenylethylene/tetraphenylethylene large conjugate system is obtained; the monoamine compound is subjected to a reaction with halogenated nitrobenzene, such that a dinitro monomer comprising triphenylamine and the triphenylethylene/tetraphenylethylene large conjugate system is obtained; and the dinitro monomer is reduced into the novel diamine compound, such that the novel functional diamine compound comprising triphenylamine and a triphenylethylene/tetraphenylethylene structure is obtained. The synthesis method provided by the invention is simple. Purification is easy. The method is suitable for industrial productions. The synthesized diamine compound has a significant aggregation-induced emission property, and can be used for synthesizing high-performance and functional polymers such as polyamide, polyimide, polyamideimide, polyesterimide, and the like.

Fluorescence-enhanced organogelators with mesomorphic and piezofluorochromic properties based on tetraphenylethylene and gallic acid derivatives

Two novel aggregation-induced emission compounds derived from tetraphenylethylene and gallic acid were synthesized and characterized. Both of the emission compounds possessed mesomorphic properties and exhibited mesomorphic phases over a wide temperature
