ABSTRACT:
The invention relates to a compound having the general Formula I ##STR1## in which one of the groups R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 represents an ionophoric moiety and the remaining groups each independently are hydrogen, a lipophilic or hydrophilic group or a reactive group for coupling to a polymer or a biomolecule, or R.sub.2 forms an aromatic ring system together with R.sub.3 and R.sub.5 forms an aromatic ring system together with R.sub.6.
The compound of the invention is useful as a luminescence indicator for alkali ions.
