Blending conjugated polymers without phase separation for fluorescent colour tuning of polymeric materials through FRET

Abstract

The fluorescence properties of conjugated polymer blends were investigated using a combination of excitation energy donor and acceptor conjugated polymers encapsulated by identical cyclic sidechains. Wearing this ‘uniform’, the polymers did not phase-separate in the blends. As such, these polymers provide an effective ensemble for designing fluorescent polymeric materials.
