Wang, Jing; Liang, Jing; Liu, Xu; Xiao, Han; Dong, Fuping; Wang, Yilin; Shu, Xin; Huang, Furong; Liu, Hai-Bo published the artcile< Thiazoline-pyrene selective and sensitive fluorescence ""turn-on"" sensor for detection of Cu2+>, Recommanded Product: 4,5-Dihydrothiazole-2-thiol, the main research area is thiazoline pyrene selective sensitive fluorescence sensor copper detection; Cu2+ detection; Fluorescence; Pyrene; Thiazoline; “Turn-on” sensor.
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.
