Six
polyoxo-titanium clusters (PTCs) with varying nuclearities containing
Ti–N bonds and heteronuclearity, namely, [Ti6(μ3-O)2(μ2-O)2(O3P-Phen)2(OiPr)10(1-hbta)2] (PTC-37), Ti8(μ3-O)2(μ2-O)2(O3P-Phen)2(OiPr)16(adn)2(NO3)2] (PTC-38), [Ti4(μ3-O)(μ2-O)(μ2-OiPr)2(OiPr)4(O3P-Phen)3(1,10-phn)](HOiPr) (PTC-39), [Ti4(μ3-O)(μ2-OiPr)3(OiPr)5(O3P-Phen)3(Im)] (PTC-40), [Ti4(μ3-O)(μ2-OiPr)3(OiPr)5(O3P-Phen)3(Im)][Ti3M(μ3-O)(μ2-OiPr)3(OiPr)3(O3P-Phen)3(Im)] (M = Co for PTC-41 and M =
Zn for PTC-42; O3P-Phen = phenyl phosphonate,
1-hbta = 1-hydroxy benzotriazolate, adn = adenine, 1,10-phn = 1,10-phenanthroline,
Im = imidazolate, and OiPr = isopropoxide) were prepared
as crystalline samples and structurally characterized. Simultaneous
doping of nitrogen and transition metal heteroatoms into the Ti–O
clusters created complex chemical environments in the resulting hybrid
materials. Thus, photocatalytic methylene blue degradation studies
were performed to understand structure–property relationships
in these Ti cluster-based materials. The complex chemical environment
created in these novel molecular clusters had proved to exhibit ligand-dependent
photocatalytic activities under normal sunlight. Adenine-functionalized PTC-38 presented moderate activities, while other PTCs all
show rapid dye degradation.
