Abstract:

We have fabricated unilayer electroluminescent devices from soluble polyp-pyridine PPy. The solubility of PPy in weak acids allows direct spin casting of the polymer films. The electroluminescence EL spectrum peaks at 2.5 eV 497 nm corresponding to white light weighted toward the blue end of the spectrum. The photoluminescence PL spectrum peaks at 2.35 eV 530 nm. The operating voltages of the devices ranged from 4 to 12 V with current densities of 6 to 8 mAsq mm. We compare our devices with similar blue emitting devices based on polyp-phenylene PPP. jg p.2
