Covalently immobilized fluoroionophores for optical ion sensors

摘要

Compounds, constructed in modular manner, of formula (I),whereinI 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 andR01, R02 and R03 are each independently of the others a direct bond or a bridging group.The compounds may be used in immobilized 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.
