COVALENTLY IMMOBILISED FLUOROIONOPHORES FOR OPTICAL ION SENSORS

摘要

Compounds, constructed in modular manner, of formula (I), wherein I is the monovalent residue of an ionophore, F is the monovalent residue of a fluorophore, G is a functional group, T is a trivalent organic radical and R01, R02 and R03 are each independently of the others a direct bond or a bridging group. The compounds may be used in immobilised form as active components in polymer membranes of optical sensors for the detection of ions. The sensors are distinguished by a long usable life and a high degree of sensitivity.
