reaction wherein the feed ratio of the latter is varied from 0.125 to 5.0 mol% to fine tune the optoelectronic properties. White light emission is demonstrated in copolymer BTZPZP-0.25 through incomplete energy transfer. The co-polymers of all films examined in the photoluminescence (PL) regions at about 430 and 570–595 nm displayed peaks originating from fluorene segments and the BTZPZP chromophore, respectively
