| Popis: | 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... |
