| Abstract: | ![]()
Fluoroionophores consisting of coumarin-153 linked to mono- and diaza-crown ethers are able to complex transition metal cations (Ni2+, Zn2+, Cd2+) and Pb2+, with concomitant large changes in photophysical properties. The stability constants in acetonitrile are higher than 3×106M–1 except for Ni2+. |
