It is an optical brightener for plastics and is suitable for use in the preparation of poly(propylene). The compound has been reported to exhibit consistently high absolute fluorescence quantum yields.Suitable for use in the preparation of poly(propylene) 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).
