Disclosed are new acridone dye derivatives having characteristic fluorescence lifetimes. Also disclosed are methods for labelling target biological materials employing the acridone dyes and use of the labelled materials in biological assays. The acridone derivatives have the following structure:
in which Z

Y; where E is a spacer group, F is a target bonding group; Y is selected from sulphonate, sulphate, phosphonate, phosphate, quaternary ammonium and carboxyl; and n is an integer from 1 to 6. The invention also relates to a set of different fluorescent acridone dye derivatives, each dye having a different fluorescence lifetime, the set of dyes being particularly useful for multiparameter analysis.
