This award in the Chemical Synthesis (SYN) program supports work by Professor Daniel L. Reger at the University of South Carolina to carry out fundamental studies on the preparation and characterization of first row transition metal complexes that are designed to have novel structures that produce unusual and useful properties. Designed ligands (groups that bind metals) bring two metals into proximity promoting bridging of the two metals by small groups (X). These M-X-M systems show unique magnetic and optical properties that can be controlled by the choice of metal and X group. Linking ligands that also contain designed functionalities that promote strong, but indirect, interactions yield new structural and bonding arrangements that test how these important indirect interactions impact on physical properties. Particularly important are ligands that have backbones with specific orientations that "project" or "amplify" the special characteristics of the ligands on to the structures of metal complexes.Graduate students working on the project train for academic positions as well as industry and government employment. Outreach collaborations with faculty and undergraduate students at two HBCU institutions nurture scientific development of minority students. Development of this chemistry is important in such diverse areas as asymmetric catalysis, non-linear optics, and sensing applications.

化学合成(SYN)项目的这一奖项支持南卡罗来纳大学的Daniel L.Reger教授开展基础研究，以制备和表征第一排过渡金属络合物，这些络合物旨在具有产生不寻常和有用性质的新颖结构。设计的配体(结合金属的基团)使两种金属接近，促进两种金属通过小基团(X)连接。这些M-X-M体系表现出独特的磁性和光学性质，可以通过选择金属和X基团来控制。连接配体也包含设计的功能，促进强烈的间接相互作用产生新的结构和成键安排，测试这些重要的间接相互作用如何影响物理性质。特别重要的是，配体具有特定方向的骨架，可以将配体的特殊特性“投射”或“放大”到金属络合物的结构上。从事该项目的研究生为学术职位以及行业和政府工作进行培训。与两所HBCU学院的教职员工和本科生开展外展合作，培养少数民族学生的科学发展。这一化学的发展在不对称催化、非线性光学和传感应用等不同领域都很重要。
