Abstract

Conjugated polymers are a novel class of semiconductors that combine the optical and electronic properties of semiconductors with the processing advantages and mechanical properties of polymers. Since the first discovery of electroluminescence from conjugated polymer, PPV has been reported by JH Burroughs, et al, in 1990, the research on polymer light emitting diodes (PLEDs) has progressed rapidly. However, the number of soluble conjugated polymers with relatively high luminescence efficiency is still limited. In this paper, a recently synthesized soluble PPV derivative MBPPV is adopted to fabricate PLEDs. We studied the photoluminescence and electroluminescence properties of MBPPV and its polyblend with PVK. The energy transfer between MBPPV and PVK matrix in different blending concentration is also investigated. The emission peak and efficiency of the device ITO/MBPPV: PVK/Alq₃/Al are 570nm and 1.35% respectively.
