title: One-dimensional assembly of chalcogenide nanoclusters with bifunctional covalent linkers.
abstract: Even though different approaches have been developed to achieve various 1D assemblies of nanocrystals, few studies have been done on the assembly of crystallographically well-defined chalcogenide nanoclusters. Here, by using bifunctional organic ligands as the directional linker, a series of one-dimensional assemblies of semiconducting chalcogenide nanoclusters have been prepared and characterized. The synthetic method allows for the preparation of differently sized tetrahedral nanoclusters that are joined together with organic linkers of different length and rigidity. Multiple linking modes between nanoclusters and organic ligands are revealed in four different assemblies that also exhibit size-dependent optical properties.
