Potentiostat - cyclic voltametry research for N,S-hybrid ligands and binuclear transition metal complexes

恒电位仪是一种在循环伏安法过程中用于电化学分析的仪器。该恒电位仪扩展了Bierenstiel博士的有机金属研究项目，在该项目中，他使用电化学来研究提出的新材料，并进行仿生金属酶研究。循环伏安实验中收集的数据将有助于研究和解释新生成的复杂体系中的电子转移过程，并允许确定所提出的金属-配体和金属-金属相互作用。Bierenstiel正在开拓新的领域，开发能够结合一种或多种过渡金属的含氮和含硫的配体系统。所谓的N，S-配体是含有硬(氮)和软(硫)施主原子的杂化化合物，有助于它们与硬过渡金属和软过渡金属结合。杂化配体表现出对催化至关重要的半活性性质，并且还具有非无害的电子性质。新的N，S-配体相互作用模拟了基于氨基酸的生物活性金属中心，在酶研究中对于研究氧化还原活性电子转移酶至关重要，例如在氢酶中。氢酶在活细胞的呼吸过程中起着重要作用。N，S配体还有助于创造新材料，例如一维含金属聚合物，可用于具有独特电磁性能的新材料，具有潜在的通信技术应用。

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.
