项目摘要

A potentiostat is an instrument used for electrochemical analysis in a process called cyclic voltametry. The potentiostat expands Dr. Bierenstiel's organometallic research program in which he uses electrochemistry to study proposed new materials and conduct biomimetic metalloenzyme research. Data gathered in cyclic voltametry experiments will help to study and interpret electron transfer processes in newly-created complex systems and allow the determination of proposed metal-ligand and metal-metal interactions.Dr. Bierenstiel is breaking new ground by developing nitrogen- and sulfur-containing ligand systems that are capable of binding one or more transition metals. The so-called N,S-ligands are hybrids that contain hard (nitrogen) and soft (sulfur) donor atoms, and are useful for their ability to bind to both hard and soft transition metals. The hybrid ligands exhibit hemilability properties that are pivotal for catalysis, and have also non-innocent electronic properties.The new N,S-ligand interactions mimic biological amino acid-based active metal centres and are crucial in enzyme research for the study of redox-active electron transfer enzymes found, e.g., in hydrogenases. Hydrogenases have an important role in the respiratory process of living cells. The N,S-ligands are also useful for the creation of new materials, such as one-dimensional metal-containing polymers that can be used for new materials with unique electronic and magnetic properties with potential use in communication technology applications.

恒电位仪是一种用于电化学分析的仪器，其过程称为循环伏安法。恒电位仪扩展了Bierenstiel博士的有机金属研究计划，在该计划中，他使用电化学来研究拟议的新材料并进行仿生金属酶研究。循环伏安法实验中收集的数据将有助于研究和解释新创建的复杂系统中的电子转移过程，并允许确定拟议的金属-配体和金属-金属相互作用。Bierenstiel博士正在开发能够结合一种或多种过渡金属的含氮和含硫配体系统。所谓的N，S-配体是含有硬（氮）和软（硫）供体原子的杂化物，并且由于它们结合硬和软过渡金属的能力而有用。这些杂化配体表现出对催化至关重要的半不稳定性，并且还具有非无辜的电子性质。新的N，S-配体相互作用模拟基于生物氨基酸的活性金属中心，并且在酶研究中对于氧化还原活性电子转移酶的研究至关重要，例如，在氢化酶中。氢化酶在活细胞的呼吸过程中具有重要作用。N，S-配体也可用于产生新材料，例如一维含金属聚合物，其可用于具有独特电子和磁性的新材料，具有在通信技术应用中的潜在用途。
