✦ Synopsis

Poly(2-benzoyl-1,4-phenylene) (PBP) and poly(2,5-dibenzoyl-1,4-phenylene) (PDBP) were synthesized by coupling polymerization using a Ni catalyst of 2,5dichlorobenzophenone and 2,5-dichloro-1,4-dibenzophenone, respectively. These polymers are soluble in common organic solvents, have high thermal stability and show bright blue photoluminescence. Light-emitting diodes fabricated with these polymers as the active layer emit blue electroluminescence with wavelength at 433 nm for PBP and 475 nm for PDBP.
