Organic-inorganic hybrid matrix doped with alkenyldiazenido complexes of molybdenum
چکیده انگلیسی
New molecular systems based on conjugated groups, trans-[FMo(NNCHCHCHCHCHCH2CH3)(Ph2PCH2CH2PPh2)2][BPh4] have been synthesized and characterized. This complex was immobilized in hybrid organic-inorganic matrix obtained by sol-gel. The hybrid matrix of these organically modified silicates, classified as ureasil formed by poly(oxyethylene) chains [POE, (OCH2CH2)n] grafted to siloxane domains by means of urea cross-linkages. All of the new materials were characterized by thermal analysis (DSC), surface analysis (XPS) and spectroscopic methods (FTIR and UV/vis), to gather information on the modifications introduced by the molybdenum complex in hybrid organic-inorganic matrix, as well as on the immobilized complex integrity. The immobilization of the metal complex in the hybrid matrix has kept their integrity, although some distortions can be observed caused by steric effects imposed by the structure of hybrid matrix or/and by interactions between the metal complex and some groups of the hybrid matrix.
