一种稳定苝酰亚胺自由基二聚体的合成方法

A synthesis method of stable perylene imide radical dimer

自由基具有高化学活性,在不良溶剂和固态条件下极易发生二聚反应,形成二聚体。自由基离域的π-电子在单电子占据轨道上发生相互作用形成饼型键,自由基分子间通过流动的饼型键连接形成二聚物。利用化学合成方法,制备出一种能够在环境中稳定存在的苝酰亚胺自由基二聚体,运用质谱、红外、核磁等手段检测其结构,为合成稳定自由基二聚体提供一种新思路。

Free radicals have high chemical activity,so they are prone to dimerization reactions and form dimers under adverse solvent and solid conditions.Theπ-electrons of free radical delocalization interact with each other on a single electron occupied orbital to form a pie like bond,and free radicals are connected to form dimers through flowing pie like bonds.A perylene imide radical dimer that can exist stably in the environment is prepared by chemical synthesis.Its structure is detected by mass spectrometry,infrared spectroscopy,nuclear magnetic resonance and other means.This offers a new idea for the synthesis of stable radical dimer.
