title: From single-molecule precursors to hybrid ZnS nanostructures.
abstract: A series of coordination compounds containing [Zn(amine)]2+ cationic complexes and alkyldithiocarbamates (RR'dtc-), as counter anions, are reported here: [Zn(amine)x][RR'dtc]2, where amine = ethylenediamine (en), diethylenetriamine (dien), 1,2-diaminopropane (dap) and, R,R' = ethyl (Et); butyl (Bu) and methyl (Me), hexyl (Hex). Hybrid nanoplates composed of hexagonal-ZnS nanoparticles and organic components were obtained after solution phase thermolysis of such precursors in oleylamine. These hybrid materials show quantum confinement effects in their optical spectra and convert into cubic-ZnS after further thermal treatment.
