An organic-inorganic hybrid material chelating a metal atom of a metal oxide matrix
103
in a pendant shape is synthesized, where the organic compound (the functional chelating agent)
104
is able to develop a function of a coloring property, a light-emitting property, or semiconductivity by chelating a metal atom. As a synthesis method, sol (a composition for coating application) including a metal alkoxide and/or a metal salt and a functional chelating agent may be prepared and the organic-inorganic hybrid material may be synthesized by sol-gel method.
Due to the above-mentioned structure, it is possible to synthesize an organic-inorganic hybrid material that has an organic group directly bonded to a metal oxide matrix and is able to develop a different function from that of a mere metal oxide. In other words, it is possible to realize a functional organic-inorganic hybrid material that develops a coloring property, a light-emitting property, or semiconductivity due to the organic group directly bonded to the metal oxide matrix.

Twenty-four organotin(IV) N,N-disubstituted hydroxylamines of the formula R2SnL2 (R = n-C4H9 and C6H5; LH = N,N-disubstituted hydroxylamines) and (C6H5)3SnL (LH = as above) have been synthesized by the reaction of organotin(IV) chlorides and hydroxylamines in presence of triethylamine in benzene medium. UV, IR, NMR and Mossbauer spectroscopic techniques have been utilized for the characterization and elucidation
