詳細

4,4′-Bis(2-benzoxazolyl)stilbene (BBS) is reported to exhibit consistently high absolute fluorescence quantum yields and a monoexponential lifetime in solutions. The photophysics of BBS dispersed in poly(propylene) (PP) films has been investigated. BBS is reported as a food-grade dye. BBS is also reported as excimer-forming, photoluminescent chromophore.

アプリケーション

4,4′-Bis(2-benzoxazolyl)stilbene (BBS) is suitable for use in the preparation of poly(propylene) (PP) films containing different concentrations of BBS. BBS may be employed as a viscosity-sensitive fluorophore to investigate the curing parameters in fabrication of UV-cured automotive organic protective coatings. BBS may be used in the preparation of polymeric film sensors based on excimer luminescence and responsive to both mechanical and temperature stress, by its dispersion into a thermoplastic aliphatic biodegradable polyester [poly(1,4-butylene succinate).

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
