Extremely light doping of organic crystals with highly fluorescent molecules enhances the luminescence provided the exciton diffusion length is long enough to reach the dopant and have the exciton energy transferred to the dopant. We present a comprehensive study of singlet exciton diffusion in a brightly luminescent doped semiconductor crystal. The high potential of this material is demonstrated by fabricating solution-processed organic light-emitting transistors. As featured in: ISSN 2050-7526 REVIEW ARTICLE Jihyun Kim et al.

Abstract
The design of light-emitting crystalline organic semiconductors for optoelectronic applications requires a thorough understanding of the singlet exciton transport process. In this study, we show that the singlet exciton diffusion length in a promising semiconductor crystal based on furan/phenylene co-oligomers is 24 nm. To achieve this, we employed the photoluminescence quenching technique using a specially synthesized quencher, which is a long furan/phenylene co-oligomer that was facilely implanted into the host crystal lattice. Extensive Monte-Carlo simulations, exciton–exciton annihilation experiments and numerical modelling fully supported our findings. We further demonstrated the high potential of the furan/phenylene co-oligomer crystals for light-emitting applications by fabricating solution-processed organic light emitting transistors.
