Resumen:
The synthesis, characterization, structural analysis and fluorescence properties of two rhodamine 6G derivatives are described. Compound I, (3´,6´-bis(ethylamino)-2´,7´-dimethyl- 2-(methylcianide)spiro[isoindole-1,9´-xanthen]-3(2H)-one) is the propargylamine (CN) derivative, and compound II, the γ-Aminobutyric acid (GABA) derivative ((3´,6´-bis(ethylamino)-2´,7´-dimethyl-3-oxospiro [isoindole-1,9´-xanthen]-2(3H)-yl)butyric-acid). Both structures are compared with four similar ones from the Cambridge Structural Database (CSD), and the interactions involved in the stabilization are analyzed using the Atoms in Molecules (AIM) theory. Finally, a single crystal in-situ reaction study is presented, carried out by fluorescence methods, which allowed to follow the "opening" of the spirolactam ring in the solid phase.
