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 N
2
or N
2
O. The invention also relates to methods for preparing such compounds and to the use of these compounds for optical microscopy and imaging techniques.
本发明涉及以下通式G1-G4(I)的新型光致发色基础或羧基吡咯烷衍生物,其中: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;包括吸收紫外光的色团,经过254-490 nm的光解作用(最好在375-420 nm下),产生荧光的罗丹明或羧基吡咯烷衍生物和小的无毒碎片,例如N2或N2O。本发明还涉及制备这种化合物的方法以及将这些化合物用于光学显微镜和成像技术的使用。
