Abstract
A series of novel soluble conjugated copolymers derived from 9,9-dioctylfluorene (DOF) with metal-free and Pt (II) tetraphenylporphyrin (TPP) were synthesized via palladium-catalyzed Suzuki coupling reaction, with TPP content in the copolymers of 0.5%, 1%, 5%, 20% and 50% respectively. Platinum (II) (Pt) were incorporated into the copolymers by reaction of the copolymers with PtCl 2. Emission from DOF segment was completely quenched at very low metal-free TPP content (1%). The copolymers of DOF-co-TPP emit saturated red emission that is red-shifted slightly with increasing the TPP contents. After Introducing Pt, the emission peak of the copolymers is blue-shifted. Electroluminescent (EL) quantum efficiency of the devices based on the copolymers was 0.12% for copolymer with 5% TPP content and EL efficiency PFO-PtTPP was 0.15% for metal complex with 1% PtTPP content.
