Abstract

Four novel benzothiazolyl modified crown ethers, non-cyclic crown ethers (podands) 1 and 2, 4-(2-benzothiazole)benzo-15-crown-5 (3) and dibenzothiazole dibenzo-18-crown-6 (4) were synthesized from 2-aminobenzenethiol. The photophysical behaviour and the binding ability of 1-4 with some alkali metal and alkaline earth metal cations were investigated by UV-VIS spectrometry. The result obtained indicates that 4 displays high selectivity to potassium ion.
