一般描述
据报道，4,4′-双(2-苯并噁唑基)二苯乙烯(BBS)可在溶液中表现出稳定的高绝对荧光量子产量和单指数寿命。分散在聚丙烯（PP）膜中的BBS的光物理学已得到研究。BBS据报道是一种食品级染料。 BBS也被报道为准分子形成的光致发光生色团。
应用
4,4′-双(2-苯并噁唑基)二苯乙烯(BBS)适用于制备含有不同浓度BBS的聚丙烯（PP）膜。BBS可用作粘度敏感的荧光团，用于研究在UV固化的汽车有机保护涂层制造中的固化参数。BBS可用于制备基于准分子发光的聚合物薄膜传感器，并通过分散成热塑性脂肪族可生物降解型聚酯[聚（1,4-丁二酸丁二醇酯））来对机械和温度应力产生响应。

An automated analytical system has been implemented for the high-throughput optimization of processing conditions such as curing parameters in fabrication of UV-cured automotive organic protective coatings. Selection of optimum process conditions of combinatorial arrays of coatings is essential to correlate

In solution, 4,4'-bis(2-benzoxazolyl)stilbene (BBS) was found to exhibit consistently high absolute fluorescence quantum yields (Φ(fl) ≥ 0.88) and a monoexponential lifetime, both independent of BBS concentration. The BBS steady-state and time-resolved photophysics were investigated by different techniques to understand the
