Copolymerization was shown to be an effective way to manipulate the charge transfer emission with minimal interferences from the stacking of the large PAMs. To further modulate the degree of charge transfer and also to reduce the potential interactions among monomer units when larger aromatic structures are introduced, copolymerization was employed for the TSCT polymer synthesis. We first copolymerized 2VN and styrene in a random manner using PDI-tetraBr as the initiator.
