Descripción

Descripción general

4,4′-Bis(2-benzoxazolyl)stilbene (BBS) is reported to exhibit consistently high absolute fluorescence quantum yields and a monoexponential lifetime in solutions.[1] The photophysics of BBS dispersed in poly(propylene) (PP) films has been investigated.[2] BBS is reported as a food-grade dye.[3] BBS is also reported as excimer-forming, photoluminescent chromophore.[4]

Aplicación

4,4′-Bis(2-benzoxazolyl)stilbene (BBS) is suitable for use in the preparation of poly(propylene) (PP) films containing different concentrations of BBS.[2] BBS may be employed as a viscosity-sensitive fluorophore to investigate the curing parameters in fabrication of UV-cured automotive organic protective coatings.[5] 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).[3]
