Resumen:
The synthesis, characterization, structural analysis and fluorescence propertiesof two rhodamine 6G derivatives are described, namely a propargylaminederivative, 30,60-bis(ethylamino)-20,70-dimethyl-2-(methylcyanide)spiro[isoindole-1,90-xanthen]-3(2H)-one (I), and a -aminobutyric acid (GABA)derivative, 30,60-bis(ethylamino)-20,70-dimethyl-3-oxospiro[isoindole-1,90-xanthen]-2(3H)-yl)butyricacid (II). Both structures are compared with foursimilar ones from the Cambridge Structural Database (CSD), and theinteractions involved in the stabilization are analyzed using the atoms inmolecules (AIM) theory. Finally, a single-crystal in-situ reaction study ispresented, carried out by fluorescence methods, which enabled the ?opening? ofthe spirolactam ring in the solid phase.
