bay‐position of perylenes and a new route to benzo[ghi]perylenes and coronenes are presented. Irradiation with light leads to an electrocyclic reaction of the newly formed triazole ring(s) with the neighbouring bay‐positions of the perylene core and after oxidation by air, the benzo[ghi]perylenes and coronenes are obtained. By using Newkome dendrimers as substituents for perylene diimides (PDIs), water solubility
提出了在per的海湾位置发生点击反应,并提出了新的苯并[ ghi ] per和Coronenes路线。光照射导致新形成三唑环的与苝芯的相邻间隔位和通过空气氧化后的电环化反应(一个或多个),[苯并GHI ]得到苝和coronenes。通过使用Newkome树状大分子作为per二酰亚胺(PDI)的取代基,去除叔丁基保护基团后即可实现水溶性。通过吸收光谱和荧光光谱研究了海湾官能化的PDI,苯并[ g ] per和Coronenes的聚集和光学性质。
