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.

制备了由氨基酸（HAlaOMe、HValOMe、HGlyOEt、HPheOMe和HLeuOMe）或乙醇胺衍生的二硫代氨基甲酸镍配合物。此外，利用这些配合物在衬底上形成了结晶膜。本研究采用的衬底有硅片（有和没有表面氧化层）、铜、钛、镍、氧化铜、玻璃、氧化铝。生长结晶膜的过程如下：在络合物的饱和溶液中，基底浸泡一天，观察到晶体沉积为混凝土。结果表明，所有的配合物都没有在硅片的镜面上结晶。此外，由氨基醇组成的络合物在无基板上分离出晶体。由氨基醇衍生的络合物不能在基质的任何表面形成晶体。另一方面，除硅以外的衬底表面上的晶体膜可以由氨基酸给予的某些配合物生长。例如，Val和Ala的配合物在金属表面形成均匀的结晶膜，但它们应该只在任何氧化物表面形成结晶岛。相反，Gly衍生物在氧化铜衬底上形成均匀的膜晶体，而不能在金属衬底上形成晶体。因此，Gly导数应该提供表面识别能力。在硅晶片蚀刻后，本研究中使用的所有配合物都不能在硅晶片上生长出晶体膜，在扭结或阶地分裂中可以识别出晶体沉积。这表明，表面能的不同会影响晶体的核形成。这些复合物在低温下比较容易分解，并且利用特定的晶体沉积对陶瓷表面进行图案化，从发现可以形成陶瓷晶体的物质到陶瓷表面都是可以期待的。
