Abstract:

The fluorescence properties of N,N-di(2-carboxyethyl)-p-anisidine (I) in solvents of various nature and in the crystalline state have been studied at room temperature (273 K) and at the boiling point of liquid nitrogen (77 K). Fluorescence in aqueous solutions of I with protonated (lambda(ex)/lambda(max)(fl) = 225/290 nm) and unprotonated (lambda(ex)/lambda(max)(fl) = 270/380 nm) amino nitrogen has been detected. On going from aqueous solutions to nonaqueous, the fluorescence band of unprotonated I experiences a blue shift and its intensity rises. The fluorescence intensity of the band in aprotic polar solvents is higher than that in protic solvents. A linear dependence of the fluorescence intensity of deprotonated I on Cu(II) concentration (ranging from 1.0 to 5.0 mg/dm(3)) in aqueous solution has been found. The fluorescence intensity of I in aqueous solutions at 77 K and pH 1-6 has been shown to increase in the presence of Zn(II) (1-170 mg/dm(3)) and Cd(II) (2-330 mg/dm(3)) although a similar dependence is not observed at 293 K.
