摘要
以L-谷氨酸为底物,设计并合成了具有双引发位点和双配合位点的X型结构原子转移自由基聚合(ATRP)引发剂.两个引发位点可以聚合形成两条聚合物链,而两个配合位点可与功能纳米粒子表面配位.该引发剂合成的聚合物可用于硒化镉、无机钙钛矿等无机光电转换纳米粒子的修饰,提高聚合物在纳米粒子表面的接枝密度,并提高纳米粒子在聚合物中的分散性.
Abstract
An X-type ATRP initiator based on L-glutamic acid,featuring dual initiation and coordination sites,has been designed and synthesized.This unique structure allows simultaneous growth of two polymer chains and efficient anchoring to functional nanoparticles.The resulting polymers are ideal for modifying inorganic optoelectronic nanoparticles like cadmium selenide and inorganic perovskites.These modifications enhance polymer grafting density and improve nanoparticle dispersion in the polymer matrix,potentially boosting the performance of nanocomposites in various applications.
