A thiazoline and pyrene containing sensor 1 (I) was synthesized via 1-pot reaction and used as a highly selective and sensitive fluorescence turn-on sensor for Cu2+ detection, via the fluorescence enhancement of pyrene monomer emission. The 2:1 stoichiometry of 1 and Cu2+ was calculated from Job’s plots based on fluorescent titrations, and the complexation of 1 with Cu2+ was also supported by mass spectra, FTIR spectra, 1H NMR spectra and d. functional theory anal. The fluorescence intensity of 1 at 389 nm and 410 nm increased significantly upon the addition of Cu2+. Limit of detection and association constant value of 1-Cu2+ were calculated using standard deviations and linear fittings, resp. 1 Was active for Cu2+ detection in the wide pH range of 2.0-11.0. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5SDS of cas: 80480-15-5).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.SDS of cas: 80480-15-5
