Abstract
Light-emitting diodes using Langmuir-Blodgett films of quinquethiophen e as the emitting layer have been fabricated, and electrically and opt ically characterized. By utilizing additional layers of electron-trans porting materials, the emitting material thickness has been reduced do wn to a single monolayer without serious decrease in the quantum effic iency. These electronic devices are valuable tools for studying carrie r injection and transport, exciton formation, and quenching on a real molecular scale.
