Abstract

The invention relates to a multifunctional polyurethane derivative containing a triarylamine structure and a tetrastyrene group as well as a preparation method and the application thereof. The invention aims to solve the problem that conventional multifunctional materials have few function types. The multifunctional polyurethane derivative provided by the invention is prepared by firstly synthesizing two monomers and 1,2-bis(4-hydroxyphenyl)-1,2-diphenylethylene containing a hydroxyl structure and simultaneously introducing 4,4'-diphenylmethane diisocyanate by means of copolymerization. The multifunctional polyurethane derivative has electrochromism and fluorescence sensing hole transport functions, can be used as an automotive rearview mirror material and a display material and can be used for preparing explosive detection and memory performance devices. The multifunctional polyurethane derivative provided by the invention is applied to the field of multifunctional materials.

Description

technical field [0001] The invention relates to a multifunctional polyurethane derivative containing a triarylamine structure and a tetraphenylethylene group, a preparation method and application thereof. Background technique [0002] Polyurethane (PU) has many desirable properties, such as better flexibility, greater tensile strength, higher hardness, more resistance to chemical solvents and temperature conditions, higher abrasion resistance, higher oil resistance and Longer fatigue life. Polyurethanes are also potential candidates for membrane preparation due to their good mechanical and chemical properties. Although polyurethane has excellent comprehensive properties, traditional PU has some disadvantages, such as high processing difficulty and poor solubility, which greatly limit the industrial application of polyurethane materials. Therefore, in recent years, more and more researchers have begun to pay attention to the research on the preparation and modification of p...
