The interactions between PEO-based templates and metallic centres are key in the synthesis of mesostructured materials. In low-water-content media, strong chelation between metal centres and the non-ionic polar heads leads to polymer unfolding, and thus t

Five mononuclear cis-dioxovanadium(V) complexes of tridentate Schiff bases derived from salicylaldehyde and its derivatives and 8-aminoquinoline have been synthesized and characterized.Single-crystal X-ray analyses were performed with 1 and 2 (L1 and L2 denote the Schiff-base anions derived from salicylaldehyde or naphthaldehyde and 8-aminoquinoline).While the structure of 2 was refined to a final R = 0.074 (R' = 0.055), that of 1 was refined only to R = 0.134 (R' = 0.139) due to its poor diffraction quality.The complexes contain cis-oxo groups in the equatorial plane and a trigonal-bipyramidal geometry around the vanadium at which the Schiff base binds meridionally.Photoirradiation of these complexes in CH2Cl2 yielded chloride-bound VO(3+) species, as studied using absorption and (51)V NMR spectroscopy.These species are convertible back to the dioxovanadium(V) complexes upon addition of water to the photoirradiated solution.
