This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports Professor Richard D. Adams at the University of South Carolina to synthesize new metal cluster complexes containing sulfide, disulfido and related chalcogen ligands for use in preparing new nanoscale metal sulfide materials with novel physical and catalytic properties. Investigations will include structural characterizations of metal carbonyl sulfide and disulfide complexes and reactivity studies of small, unsaturated organic molecules and metal-ligand groups at the sulfur atoms. Studies of reactivity at the metal atoms toward donor ligands and small organic molecules will also be undertaken. These compounds will be used as precursors for new nanoscale materials with novel physical and chemical properties that should lead to a deeper understanding of nanoscale material properties. Metal sulfides play key roles in materials science: in phosphors, in lubricants, as catalysts, in semiconducting and even superconducting materials. This research will lead to the synthesis of new inorganic materials and nano-materials that will exhibit novel properties for catalysis and semiconductors. Students will be trained in the design, synthesis and characterization of inorganic and organometallic compounds, and in the use of modern analytical techniques, such as infrared spectroscopy, x-ray crystallography, nuclear magnetic resonance spectroscopy, cyclic voltammetry and other types of electronic spectroscopy measurements.

这个奖项在无机，生物无机和有机化学计划支持教授理查德D。南卡罗来纳州大学的亚当斯合成了含有硫化物、二硫化物和相关硫族配体的新的金属簇络合物，用于制备具有新的物理和催化性能的新的纳米级金属硫化物材料。 调查将包括金属硫化羰和二硫化物配合物的结构表征和小的，不饱和的有机分子和金属配体基团在硫原子的反应性研究。 还将研究金属原子对供体配体和小有机分子的反应性。 这些化合物将用作具有新型物理和化学性质的新型纳米材料的前体，这应该会加深对纳米材料性质的了解。金属硫化物在材料科学中起着关键作用：在磷光体中，在润滑剂中，作为催化剂，在半导体甚至超导材料中。这项研究将导致合成新的无机材料和纳米材料，这些材料将表现出催化和半导体的新特性。 学生将接受无机和有机金属化合物的设计，合成和表征方面的培训，以及现代分析技术的使用，如红外光谱，X射线晶体学，核磁共振光谱，循环伏安法和其他类型的电子光谱测量。
