Abstract

The invention relates to novel fluorescent dyes with phosphorylated hydroxymethyl groups, a method for preparing the same as well as to their use in imaging techniques. The fluorescent dyes are coumarin, rhodamine or BODIPY dyes having of one of the following general formulae I-III:wherein W=OP(O)Y1Y2 or P(O)Y1Y2, where Y1 and Y2 independently denote any of the following residues: OH, O(−), ORa and ORb, NHRa and NHRb, NRaRb and NRcRd, ORa and NHRb, ORa and NRbRc, NHRa and NRbRc; and any salt thereof.
