Abstract: The present invention relates to novel red fluorescent sensors for detecting metal ions, preferably zinc ions, which have a chemical structure corresponding to a compound of general formula I. These sensors are very useful for determining the concentration and distribution of zinc in living cells or tissues, preferably in a laser microscopic assay.
