Abstract

Abstract The present invention provides resorufin derivatives of the general formulae: <IMAGE> wherein R1, R2, R3, R4 and R5, which can be the same or different, are hydrogen, halogen, carboxyl, carboxamido, lower alkoxycarbonyl, cyano or nitro groups or lower alkyl or lower alkoxy radicals, which can be substituted by carboxyl, carboxamido, lower alkoxycarbonyl, cyano or nitro groups, and wherein R4 and R5 can together also represent an anellated aromatic residue, Z is a bridge member, A is the residue of a ligand and n is a whole number of from 1 to 200. The present invention also provides processes for the preparation of these resorufin derivatives, as well as intermediates for the preparation thereof.
