Description

technical field [0001] The invention relates to a poly(p-phenylene) derivative containing a carbazole structure and a cyano group, a preparation method and 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 enhance i...
