Controlled Preparation and Fluorescent Property of Luminescent Nanobowls
摘要
Abstract
This study involves the design and synthesis of four amphiphilic homopolymers with varying grafting degrees of poly(glycidyl methacrylate)-graft-fluoranthene,denoted as P(GMAm-stat-ENn).The influence of grafting degree and initial concentration on the self-assembly behavior of P(GMAm-stat-ENn)was systemati-cally investigated.The effects of concentration and water content on the optical properties of P(GMAm-stat-ENn)were explored,revealing that as the initial concentration increases,the fluorescence intensity of the nanobowls first increased and then decreased,exhibiting characteristics of both aggregation-induced emission(AIE)and aggregation-caused quenching(ACQ).Furthermore,the mechanism underlying the morphological evolution during the self-assembly process was elucidated.The results indicate that with the increase of poly-mer initial concentration and grafting degree,the opening size of the synthesized nanobowls gradually decreases while the particle size increases.This study provides new insights for the design and development of novel lumi-nescent functional nanomaterials.关键词
