Abstract
The present invention relates to novel photoactivable rhodamine or carbopyronine derivatives of the following general formulae G1-G4 (I), G1: A1=O, A2=N, A3=C; G2: A1=S, A2=N, A3=C; G3: A1=O, A2=O, A3=N; G4: A1=S, A2=O, A3=N; comprising UV light absorbing chromophores which after photolysis by irradiation at 254-490 nm (preferably at 375-420 nm) generate fluorescent rhodamine or carbopyronine derivatives and small non-toxic fragments such as Nor NO. The invention also relates to methods for preparing such compounds and to the use of these compounds for optical microscopy and imaging techniques.
