A new luminescent copolymer containing three functional moieties was prepared. It possesses high thermal stability, good electrochemical reversibility, and good thin film- forming ability. Electrical characterization of a two-layer diode device based on the structure of ITO/CuPc/TPDPQ-FPQ/Al showed excellent electroluminescence performance.
In recent years, light-emitting diodes fabricated with organic molecules and conjugated polymers have attracted much attention due to their potential application in full color flat panel display. Among the conjugated polymers ever used in polymer light-emitting diodes, poly(p-phenylene vinylene)s (PPV), poly(N-vinylcarbazole) (PVK) and poly(3- alkylthiophene)s (P3AT) have been investigated most widely. PPV, PVK are good emissive materials as well as hole- transportation materials. P3AT, with their good solubility and chemical stability, are also promising candidate materials for the emitting layer. Furthermore, the properties of P3AT can be easily changed by the size of side chain groups. In this paper, a new kind of P3AT was synthesized, and multilayer light-emitting diodes based on the blended polymer of P3AT and PVK were fabricated. The I-V characteristics and electroluminescent spectroscopy were measured and discussed.
