The present invention relates to π-conjugated fluoroionophores, methods for their preparation, and their use and a method for determining an alkali ion. Fluoroionophoric compounds of the general formula I are described Ionophore – π-Linker - Fluorophore (I) wherein the Ionophore is an anilino containing crown ether or cryptand with one or more anilino donor moieties as electron donors, forming a stable complex with an alkali metal ion the π-Linker is an aromatic or heteroaromatic conjugative linking moiety, and the Fluorophore is an electron acceptor moiety. Variation of the ionophoric unit offers a broad spectrum of detectable K+ and Na+ -concentrations, ranging from high concentration around 800 mM down to very low concentrations around 3 mM. The fluoroionophores have great potential for application in fluorescent optode system based blood analyzing equipment for methods and kits for the determination of K+ and Na+ concentrations in biological systems, either in vitro or in vivo, using embodiments of the disclosed fluoroionophores.

receptor N‐phenylaza‐[18]crown‐6 and different fluorophoric groups with different electron‐acceptor properties (4‐naphthalimide, meso‐phenyl‐BODIPY and 9‐anthracene) and investigated their performance in organic and aqueous environments (physiological conditions). In the charge‐transfer (CT) type probes 1, 2 and 7, the fluorescence is almost completely quenched by intramolecular CT (ICT) processes involving
