The present invention provides resorufin derivatives of the general formulae: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5, 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 R.sup.4 and R.sup.5 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.
本发明提供了一般式为:##STR1##的荧红素衍生物,其中R.sup.1,R.sup.2,R.sup.3,R.sup.4和R.sup.5可以相同或不同,为氢、卤素、羧基、羧酰胺基、低碳酸酯基、氰基或硝基或低烷基或低烷氧基,可以通过羧基、羧酰胺基、低碳酸酯基、氰基或硝基取代,其中R.sup.4和R.sup.5也可以共同表示一个环接芳香残基,Z是桥接成员,A是配体残基,n为1至200的整数。本发明还提供了制备这些荧红素衍生物的方法,以及制备这些衍生物的中间体。
