Outline of Final Research Achievements

We succeeded in constructing thin-film single crystals by epitaxial growth from solution for a pair of substrate and film crystals of halogen-bridged one-dimensional Platinum(II,IV) complexes, which contain different ligands and have another crystal structures. By soaking substrates of the bromo-bridged complex with 1R,2R-diaminohexane ligand into aqueous film solution containing the analogous complex with ethylenediamine, gold thin-film single crystals of about 0.05 μm of thickness were made on surfaces of green substrates by slow epitaxial growth.
Photo-emissive isomorphic hexa-nuclear Ag(I) and Cu(I) complexes containing different pyridinethiolate derivatives were chosen for surface film and substrate crystals of epitaxial growth. By soaking substrates into chloroform film solution and concentrating it under reduced pressure, fine single crystals with yellowish green emission were crystallized by epitaxial growth on surface of red emissive substrates.
