摘要: The first guanine-based difunctional colorimetric receptor 8-[(4-nitrophenyl)azo]guanine (receptor 1) was designed, synthesized and characterized by IR, UV-vis, (1)H NMR mass spectrometric analysis. 1 able to recognize Cu(II), Zn(II) acetate ion through visible color changes in its DMSO DMSO-H(2)O (95:5, v/v) solution. binding affinity of the with chosen analytes has been estimated terms constants non-linear fittings corresponding UV-vis titration data while mode same studied spectral studies.
