Abstract
Compounds, constructed in modular manner, of formula (I), ##STR1## wherein PA1 I is the monovalent residue of an ionophore, PA1 F is the monovalent residue of a fluorophore, PA1 G is a functional group, PA1 T is a trivalent organic radical and PA1 R.sub.01, R.sub.02 and R.sub.03 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.
