摘要

我们设计并合成了一种具有先进光电特性的有机发光系统--2,5-双（5-[1,1′-联苯]-4-基噻吩-2-基）呋喃。该单晶系统以单晶形式生长，具有典型的氢聚集现象，光致发光量子产率为 29%，伏极性场效应迁移率约为 0.7（空穴）和 0.1（电子）cm2 V-1 s-1。该系统通过了激光开发适用性验证，在黄色区域表现出卓越的增益和双增益窄化发射。与结构对应物和类似系统相比，它具有更优越的光学和电学特性。该系统还可以通过加入平面谐振器结构和使用接触工程技术来实现电驱动半导体激光器，从而得到进一步发展。

Optoelectronic characteristics of furan substituted thiophene/phenylene co-oligomer single crystals for organic lasing

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.
