Blue Electroluminescent Devices Based on Soluble Poly(p-pyridine).
Abstract
We have fabricated unilayer electroluminescent devices from soluble poly(p-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 mA/sq mm. We compare our devices with similar blue emitting devices based on poly(p-phenylene) (PPP). jg p.2
