Photoactivatable turn-on fluorescence based on the photo-cleavage of the C-Br bond in 1,2-bis(5-(bromoethyl)benzoxazol-2-yl)ethane

Hao, Yongchao,Dong, Xian-Zi,Chen, Yi

, p. 3468 - 3472 (2014)

This paper describes photoactivatable turn-on fluorescence based on the photo-cleavage of the C-Br bond in 1,2-bis(5-(bromoethyl)benzoxazol-2-yl)ethane (1) in both solution and in a polymeric thin film. It was found that 1 exhibited very weak fluorescence in both solution and in a PMMA thin film, upon irradiation with 365 nm light, a strong fluorescence was detected. The strong fluorescence attributed to the photo-product resulted from the photo-induced cleavage of the C-Br bond in 1. Moreover, it was also found that the photo-cleavage of the C-Br bond in 1 can be performed using a two-photon induced process, and upon irradiation on a 1-PMMA thin film with a 780 nm femtosecond laser, finely resolved fluorescence images are obtained.

Method For Producing Bisbenzoxazoles

-

Page/Page column 6, (2010/04/23)

The invention relates to a method for producing bisbenzoxazoles that are interconnected by means of a system of conjugated double bonds, according to which o-aminophenols are reacted with dicarboxylic acids, the carboxyl groups of which are interconnected via a double bond or a system of conjugated double bonds, to form an ammonium salt, said ammonium salt being converted in the presence of dehydrogenating catalysts and solvents with a low dielectric loss into benzoxazol by means of microwave radiation.
