Synthesis of Nonconjugated TADF Polymers with Different Main Chains

Polysiloxane and polystyrene main-chain polymers were synthesized and investigated that contain the same side chains from the moieties responsible for thermally activated delayed fluorescence (TADF) at different ratios. It was shown that the polysiloxane and polystyrene main-chain polymers can be obtained from the same TADF monomers by polymer analogues reactions of hydrosilylation with polymethylsilane PMS-60 or by free-radical polymerization, respectively. Each of the polymers obtained was characterized using gel permeation chromatography (GPC) and thermogravimetric analysis (TGA). The general conclusions of the comparative studies of the polymers are presented.
