主 题：cyclization-induced emission downcycling photoluminescence polymer degradation substituent effect
摘 要：The creation of a new photoluminescent platform to study their photo physics and further applications is important in the fields of chemistry,material,physics,*** this work,we developed benzene-based fluorophores generated by chemical reactions on conjugate acceptor *** optical properties have been studied,and the large Stokes shifts,high molar extinction coefficients and quantum yields have been *** starting precursors containing bis-intercalated vinyl thioester shows no luminescence,which is turned on by the chemically triggered *** spectroscopic,crystallographic,and computational studies,cyclization-induced emission enhancement is proposed as a mean to explain the photoluminescent performances,a principle extended in the substituent incorporated ***,they were applied to the chemically triggered degradation of a polymer and achieved visual tracking,quantifying,and downcycling of the *** method for designing and developing series fluorophores and visually tracking polymer degradation represents a new photoluminescent platform,allowing its further applications.
