Summary:
This work was conducted within the graduate thesis in the laboratory of
Inorganic Chemistry of Chemistry Department of National and Kapodistrian
University of Athens. The first part is a review of the photo-catalytic systems
for hydrogen production in homogeneous catalysis. We also present the synthesis
and characterization of: [ReBr(CO)3(amphen)] (amphen = 1,10 – phenathroline – 5
– amine), [ReBr(CO)3(phendione)] (phendione = 1,10 – phenathroline – 5,6 –
dione), [ReCl(CO)3amphen], [Re(CO)3Cl{dppz-3,6-(COOEt)2}] (dppz-3,6-(COOEt)2 =
[3,2-a:2΄,3΄-c]phenazine-3,6- dicarboxylic ethyl ester). The X-ray crystal
structure of [ReBr(CO)3pq] (2) has been determined. Electrochemical and
photophysical studies have been performed to study the ability of the
[ReBr(CO)3amphen], [ReBr(CO)3(phendione)], [ReCl(CO)3(amphen)], [ReBr(CO)3pq],
[Re(CO)3Cl{dppz-3,6-(COOEt)2}], [Ga(di-o-F-p-py)-1-Ga], [Ga(tpfc)-2-Ga] and
Cu(I) complexes {[Cu(I)(dppzCOOEt)2]} to reduce protons in homogeneous
photocatalytic systems. Cobaloximes, dithiolenic complexes Ni, Co(II) complexes
{[K(NCMe)3(L6)CoII-NCMe]MeCNH2O, [K(NCMe)3(L13)CoII-NCMe]} and Cu(I)
complexes {[Cu(I)(dppzCOOEt)2]} were used as hydrogen reaction catalysts. The
mechanism of the reactions were studied by quenching fluorescence experiments.
