Poly(2,6-(4,4-bis(2-ethylhexyl)-4H-cyclopenta[def]phenanthrene)) (PCPP) is a stable blue light emitting conjugated polymer even after annealing at 150 °C or operation of the device in air. The polymers, BC-PCPP, CO-PCPP and BO-PCPP, have been synthesized by Yamamoto polymerization. The photoluminescence (PL) emission spectra of the BC-PCPP, CO-PCPP and BO-PCPP in chloroform solution show maximum peaks at 398, 387 and 384 nm, respectively. The polymer films show maximum peaks at 419, 425 and 425 and additional peaks at around 530 nm in PL spectra.
