摘要:
New complexes of cadmium iodide with 1,3-bis[2-(diphenylphosphoryl)phenoxy]propane [(CdLI2)-I-0], 1,2-bis[2-(diphenylphosphorylethyl)phenoxy]ethane [(CdLI2)-I-1, 2], and 1,8-bis[2-(diphenylphosphorylethyl) phenoxy]-3,6-dioxaoctane [(CdLI2)-I-3, 2] are synthesized and their IR spectra and crystal structures are studied. Electroanalytical characteristics of membranes of ion-selective electrodes based on L-0, L-1,L- 2, L-3,L- 2, and known crown ethers are compared for cations of alkali, alkaline-earth, and transition metals. Ligand L-3,L- 2 is the first podand with terminal diphenylphosphoryl fragments to exhibit selectivity with respect to the cadmium cation.
