Abstract | Voltage- and polarity-controlled multilayer multicolor light-emitting test devices based on pyridine-contg. conjugated polymers and derivs. of polyacetylene were fabricated and evaluated. The polymer blends of poly(pyridyl vinylene deriv.) and poly(bis(hexadecyloxy)phenylene-vinylene) and poly(di-Ph Bu acetylene) or poly(hexyl Ph acetylene) are used as the emitting material. Sulfonated poly(o-methoxyaniline) is the redox layer and ITO and Al were used as electrodes. The devices emit red light under forward bias and multiple colors of light (from orange-red to green) under reverse bias. The colors under reverse bias are controlled by the magnitude of the applied voltages. [on SciFinder(R)] |
