Calif State Univ Long Beach, Dept Chem & Biochem, Long Beach, CA 90840 USAOne of the most exciting recent developments concerning molecular architectures is the emerging field of crystalline chalcogenide superlattices that bridges two traditional but distinct areas of research: chalcogenide clusters and porous materials. By combining synthetic and structural concepts in these two areas, many crystalline solids containing spatially organized chalcogenide clusters have been created that exhibit varied properties ranging from microporosity, fast ion conductivity, and photoluminescence to narrow and tunable electronic band gaps. The potential applications of these materials extend beyond traditional areas such as acid catalysis or adsorption-based separation to include shape-or size-selective photocatalysis, solid-state ionics, and electrochemistry

Univ Calif Riverside, Dept Chem, Riverside, CA 92521 USA 电子邮件地址: [email protected], [email protected] integrating porosity with electrical or optical properties, microporous chalcogenides may have unique applications. Here we review recent advances and discuss concepts in the synthesis and crystal structure of tetrahedral clusters and their frameworks. These chalcogenides can be viewed as trivalent metal chalcogenides doped with tetra-, di-, or monovalent metal cations. Low-valent cations help to increase the cluster size, while high-valent cations have the opposite effect

Zero- and two-dimensional organization of tetrahedral cadmium chalcogenide clusters with bifunctional covalent linkers

通讯作者地址: Feng, PY (通讯作者), Univ Calif Riverside, Dept Chem, Riverside, CA 92521 USA 地址: 1. Univ Calif Riverside, Dept Chem, Riverside, CA 92521 USA 2. Calif State Univ Long Beach, Dept Chem & Biochem, Long Beach, CA 90840 USA 电子邮件地址: [email protected] examples are known in which chalcogenide clusters are assembled with organic ligands into crystallographically ordered covalent superlattices even though molecular crystals of such clusters have been known for decades. Here by using bifunctional organic ligands as the organizing force, semiconducting tetrahedral chalcogenide clusters, Cd32S14(SPh)(36), have been assembled into two-dimensional layers. In addition, a dimeric unit consisting of two core-shell-like C17Se4(SPh)(26) clusters bridged by two organic ligands has also been synthesized. In these inorganic-organic hybrid assemblies, chalcogenide clusters and bifunctional organic ligands are joined together through metal-ligand coordination bonds. A key structural feature is the presence of two organic bridging ligands between the same two clusters ( the double-bridging mode). This work demonstrates the feasibility of creating organized nanocluster-ligand superstructures through synthetic design of molecular clusters or bridging ligands
