| Outline of Final Research Achievements |
The interactions between o-phenylenediamine and alkali or alkaline earth metals such as Li+, Na+, Mg2+, or Ca2+, were investigated in solution by 1H NMR and UV-vis spectroscopy, as well as in the solid state by X-ray diffraction analysis. These structural and spectroscopic studies revealed that the type and magnitude of interactions depend on the ratio between charge and the ionic radius of the metal ions. In particular, the study structurally characterized two new opda complexes of alkali and alkaline earth metal ions, Li(opda)6opda and Ca(opda). Preliminary photochemical hydrogen-evolution reactions indicate an enhanced activity in the presence of Mg2+ or Ca2+ cations.
