Abstract

Copolymers based on fluorene and benzothiadiazole exhibit high brightness and quantum efficiencies when incorporated into polymer light-emitting diodes (PLEDs). Their emision wavelength is strongly dependent on the benzothiadiazole-containing segment of the polymer. However, the chain structure and charge-transport and -transfer processes in these materials are not well studied. This paper reports the synthesis of a structural-random (r-PF3B) and a structural-defined (s-PF3B) copolymer, poly-fluorene-co-benzothiadiazole whereas the ratio of the two co-monomers is chosen to be 75% and 25%, respectively.
