Abstract
We design and synthesise an organic lasing system, 2,5-bis(5-[1,1′-biphenyl]-4-ylthiophen-2-yl)furan, which has advanced optoelectronic properties. Grown as a single crystal, this monoclinic system exhibits typical H-aggregation and has a photoluminescence quantum yield of 29% and ambipolar field effect mobilities of approximately 0.7 (hole) and 0.1 (electron) cm2 V−1 s−1. The system is validated for its suitability towards laser development, and it exhibits excellent gain along with dual gain-narrowing emission in the yellow region. It has superior optical and electrical properties compared to its structural counterpart and similar systems. The system can be further developed by incorporating a planar resonator structure and using contact engineering techniques to realise electrically driven semiconductor lasers.
