本工作公开了一种新的有机半导体激光染料的分子设计，其显示出优异的光学性质和高鲁棒性。通过比较具有双二苯乙烯单元的公知激光分子（BSBCz），证明了呋喃部分用于增加新开发的基于呋喃的衍生物（BPBFCz）中的热稳定性和光稳定性的适合性。新衍生物在溶液和掺杂薄膜中均表现出接近100%的高光致发光量子产率和接近10（9）s（-1）的辐射速率常数，并且它们在纯薄膜中的性质也是优异的。BPBFCz材料的放大自发辐射（ASE）阈值被发现是非常低的（
A new molecular design for organic semiconductor laser dyes showing excellent optical properties and high robustness is disclosed in this work. The suitability of a furan moiety for increasing the thermal and photostability in newly developed furan-based derivatives (BPBFCz) is demonstrated by comparing a well-known laser molecule (BSBCz) having a bis-stilbene unit. The new derivatives exhibited high photoluminescence quantum yields of nearly 100% and radiative rate constants of similar to 10(9) s(-1) in both solution and doped films, and their properties were also excellent in neat films. The amplified spontaneous emission (ASE) thresholds of the BPBFCz materials were found to be very low (
