This was a five -step process involving: diazo coupling reaction, chloridization, condensation, hydrolysis, condensation respectively.
这是一个五步反应，包括重氮化偶合反应、氯置换反应、缩合反应、水解反应、缩合反应。
Poly (N-vinyl carbazole) was modified to prepare azo-PVK by post-azo-coupling reaction with diazo salt as raw material using phase-transfer catalysts.
我们以聚乙烯咔唑为偶合组分，和发色基团对硝基苯重氮盐在相转移催化剂存在下，采用后重氮偶合方法，制备出偶氮化聚乙烯咔唑。
