Abstract
The effect of organic field-effect transistors (OFET) in fluorene end capped fused bithiophene oligomers (BFTT) was examined. Investigations show that the long wavelength emission from the ketonic defects was observed in the photoluminescence spectra of BFTT films. It was found that the formation of keto defects leads to a rapid degradation in the performance of BFTT. The results show that methods were developed to reduce the photo-degradation process of OFET based on fluorene-based oligomers and polymers.
