Abstract

Naphthalene ring structure and cyano containing poly-p-styrene derivative and preparation method and application thereof. The invention relates to a naphthalene ring structure and cyano containing poly-p-styrene derivative and a preparation method and application thereof. The invention provides the naphthalene ring structure and cyano containing poly-p-styrene derivative and the preparation methodand application thereof. According to the method, a naphthalene ring structure containing dialdehyde monomer is synthesized, and then, the naphthalene ring structure and cyano containing poly-p-styrene derivative is prepared; the material is applied to electrochromic materials, hole-transport materials, garnishing materials and automobile rear-view mirror materials as a photoelectric material; the material can also be applied to detection on organic acids and explosives. The derivative is applied to the fields of photoelectric detection and display.

Description

technical field [0001] The invention relates to a poly(p-phenylene) derivative containing a naphthalene ring structure and a cyano group, a preparation method and an application thereof. Background technique [0002] Poly(p-phenylene vinylene) (PPV) is a kind of high-temperature-resistant polymer material with outstanding comprehensive properties. It has good chemical stability, excellent dielectric properties and radiation resistance, etc. It can be prepared into films, composite materials, insulating paints, Capacitor materials are widely used in aerospace, electroluminescence, sensors and other fields. Although poly(p-styrene) has excellent comprehensive properties, traditional PPV has some disadvantages, such as high processing difficulty, poor solubility, poor film-forming strength, poor flexibility and easy cracking, etc., which greatly limits the application of poly(p-styrene) in the industry. on the application. Therefore, we introduced alkoxy side chains on PPV to...
