Abstract

The invention relates to a polyurethane derivative containing a triarylamine structure and a tetrastyrene group, a preparation method and application thereof. The invention aims to solve the problem that the existing multifunctional material has few functional types. The method comprises the following steps: firstly, synthesizing a diamine monomer and a 1, 2-double (4-hydroxyphenyl)-1, 2-diphenylethylene containing a hydroxyl structure; introducing 4, 4'-diphenylmethane diisocyanate, and preparing by means of copolymerization. The material has the functions of electrochromism and fluorescencesensing hole transmission, can be used as an automobile rearview mirror material and display material, and can be used for preparing explosive detection and memory performance devices. The invention is applied to the field of multifunctional materials.

Description

technical field [0001] The invention relates to a 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 polyurethane and ...
