Abstract
Fluoroionophores of formula (I) whereinR06 is H or substituted or unsubstituted C1-C20alkyl,R6 is H or substituted or unsubstituted C1-C30alkyl or C1-C30alkoxy,R1 is a bridging group, andF is a residue of a fluorophore.The fluoroionophores may be covalently bound to support materials and may be used as active components in polymer membranes of optical sensors for the detection of ions. The sensors are distinguished by short response times, a high degree of sensitivity and a long usable life.
