What is the 2,2'-(1,2-Ethenediyldi-4,1-phenylene)bisbenzoxazole?

2,2'-(1,2-Ethenediyldi-4,1-phenylene)bisbenzoxazole is solid, while it's Molecular Formula is C 28 H 18 N 2 O 2 . solid 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).

What is the CAS number for 2,2'-(1,2-Ethenediyldi-4,1-phenylene)bisbenzoxazole?

The CAS number of 2,2'-(1,2-Ethenediyldi-4,1-phenylene)bisbenzoxazole is 1533-45-5.

What is 2,2'-(1,2-Ethenediyldi-4,1-phenylene)bisbenzoxazole (1533-45-5) used for?

2,2'-(1,2-Ethenediyldi-4,1-phenylene)bisbenzoxazole, also known as 4,4′-Bis(2-benzoxazolyl)stilbene (BBS), is a bright yellow crystalline powder with a greenish shade. It is a solid with a melting point of 355-360°C and a purity of at least 98.5%. BBS is known for its consistently high absolute fluorescence quantum yields and a monoexponential lifetime in solutions. It is also reported as a food-grade dye and an excimer-forming, photoluminescent chromophore.InChI:InChI=1/C28H18N2O2/c1-3-7-25-23(5-1)29-27(31-25)21-15-11-19(12-16-21)9-10-20-13-17-22(18-14-20)28-30-24-6-2-4-8-26(24)32-28/h1-18H/b10-9+
