| Research Abstract |
It was found that nickel dithiocarbamate complexes derived from amino acid esters could form complex assemblies through intermolecular hydrogen bondings between carbamoyl proton and terminal carbonyl. Especially, the complex from glycine alkyl should offer specific micro-channel structures of 0.7 nm in diameter. Such micro-pores should be derived from bent conformation of two amino acid moieties of the complex in trans position. Further such complexes could form clathrates with dioxane or bipyridine as proton acceptor. Additionally, nickel dithiocarbamates from amino acids existed in 1D chain structure through complimental hydrogen bondings at terminal carboxyls.
In order to immobilize these complexes onto a silicon surfaces, some attempts were done, and we could obtain a complex-terminated silicon via. the following three routes ;
1. Reactions of hydrogen-terminated silicon with the nickel dithiocarbamates having terminal alkenyl moieties.
2. Surface reactions of aminoalkyl-terminated silicon with nickel(II) ion and carbon disulfide.
3. Surface reactions of dithiocarbamoylalkyl-terminated with nickel(II) ion, diethylamine and carbon disulfide. The dithiocarbamoylation was done by the reaction of aminoalkyl-terminated silicon with carbondisulfide and triethylamine.
