项目摘要

Nickel(II) dithiocarbamate complexes derived from amino acids (HAlaOMe,HValOMe,HGlyOEt,HPheOMe, and HLeuOMe) or ethanolamine were prepared. Furthermore, formation of a crystalline membrane on the substrates was examined using these complexes. Substrates employed in this study were silicon wafer (with and without surface oxide layer), copper, titanium, nickel, copper oxide, glass, alumina. The procedure to growth a crystalline membrane is as following ; to a saturated solution of the complex, the substrates were immerced for a day, and crystal deposition was observed to be concrete. As a result, all the complexes did not crystallize onto the mirror surface of silicon wafer. In addition, the complex composed from amino alcohol separated a crystal on no basal plate. The complexes derived from aminoalcohol cannot give crystals on the any surfaces of the sustrates. On the other hand, crystalline membranes on the surface of the substrates other than silicon can be grown from some complexes given from amino acids. For example, complexes from Val and Ala formed uniform crystalline membranes on metal surfaces, but they should give only crystalline islands on the surface of any oxides. On the contrary the Gly derivative formed uniform membrane crystal on copper oxide substrates, but it can not form crystals on the metal substrates. Thus, the Gly derivative should offer a surface recognition ability.After the etching of the silicon wafer, on which no crystalline membrane can be grown from all the complexes used in this study, crystal deposition was able to be recognized in the kink or terrace division. These suggest that a difference of surface energy affects nuclear formation of a crystals. These complex comparatively disintegrates at low temperature, and the use to patterning to the ceramics surface which used specific crystal deposition from finding what can form ceramics crystal to ceramics surface can be expected.

制备衍生自氨基酸（HAlaOMe、HValOMe、HGlyOEt、HPheOMe和HLeuOMe）或乙醇胺的二硫代氨基甲酸镍（II）络合物。此外，使用这些络合物检查了在基板上的结晶膜的形成。在这项研究中采用的基板是硅晶片（有和没有表面氧化层），铜，钛，镍，氧化铜，玻璃，氧化铝。生长结晶膜的程序如下：将基底浸入络合物的饱和溶液中一天，观察到晶体沉积是具体的。结果表明，所有的配合物都没有在硅片的镜面上结晶。此外，氨基醇形成的配合物在无基板上形成晶体。氨基醇衍生的配合物不能在任何载体表面形成晶体。另一方面，在硅以外的基底表面上的结晶膜可以从氨基酸的某些复合物生长。例如，瓦尔和Ala的复合物在金属表面上形成均匀的结晶膜，但它们在任何氧化物表面上都只能形成结晶岛。而甘氨酸衍生物在氧化铜基底上形成均匀的膜状晶体，但在金属基底上不能形成晶体。因此，甘氨酸衍生物应提供表面识别能力。在蚀刻硅晶片后，其上不能从本研究中使用的所有络合物生长结晶膜，晶体沉积能够在扭结或平台分割中被识别。这表明表面能的差异影响a晶体的核形成。这些复合物在低温下相对分解，从寻找能够形成陶瓷晶体的物质到陶瓷表面，利用特定的晶体沉积对陶瓷表面进行图案化的用途是可以期待的。
