Preparation of Phenazasiline-containing Poly(arylene)s and Their Use as Functional Additives in Resins

Color variation is also important for in-dustrial applications. Thus we were optimistic of prep-aration of a copolymer with an aromatic unit tochange the color of phenazasiline. In this study, weprepared a phenazasiline-containing poly(arylene)(PAR), and used the polymer as functional additive.We also studied the fluorescence energy resonancetransfer (FRET) between the phenazasiline-containingpolymers as the probe in the transparent resin whentwo polymers were used simultaneously.EXPERIMENTALReagentReagents 2,5-bis(trimethylstannyl)thiophene,
