原位多重光学监测的本体聚合
In situ Multiple Optical Monitoring of Bulk Polymerization
摘要
Abstract
Optical visualization provides a highly sensitive,non-invasive,and straightforward approach for the in situ monitoring of bulk polymerization processes.This paper synthesized a 9,14-diphenyl-9,14-dihydrodibenzo[a,c]phenazine(DPAC)-based molecule,whose distinct excited-state conformational responses under different micro-environments enabled the monitoring of microscopic dynamic changes within the system.During the polymerization of methyl methacrylate(MMA),the system transfer from a liquid monomer to a solid polymer.Accompanying this process,the fluorescence of DPAC shifts from red to blue,reflecting the increase in local viscosity and the restriction of molecular motion.Subsequently,the gradual enhancement of phosphorescence and the extension of its lifetime indicate the rising rigidity of the polymer network.Through dual-channel monitoring based on ratio-metric fluores-cence and phosphorescence,this strategy makes the visual tracking of bulk polymerization feasible.关键词
