RUI: Metal complexes with Benzothiophene and/or NHC ligands: Synthesis and Applications

在化学系化学结构、动力学和机理B项目资助的这一项目中，克雷格M.巴德学院化学项目的安德森研究了过渡金属配合物的合成，该配合物含有通过多个配位原子与金属键合的部分。 这些化合物的光学特性和生物化学反应性取决于配体结构，可以对其进行调整以优化潜在应用中使用的特性，例如有机发光二极管（OLED）中的发射波长。 该项目增加了对金属-配体键合的理解，为开发更有效和更强大的OLED和抗癌药物提供了希望。 这项工作的一个重要组成部分是，它涉及本科生的培训，这些学生在当代化学实验室中熟练掌握科学实践。 他们通过会议发言和同行评议的期刊文章参与研究成果的传播，从而获得必要的经验，以便继续进行未来的科学研究。该项目研究与N-杂环卡宾和/或环化苯并噻吩部分或片段结合的金属配合物和环化配合物。 这些配合物在催化剂、传感器、人工光合装置、生物有机试剂等方面具有潜在的应用价值。 具体目标包括：1.铂、铱、镍与苯并噻吩和氮杂环卡宾衍生配体的金属配合物的合成与表征; 2.金属络合物的物理性质和反应性的检查;和3.探索新合成的化合物在OLED器件制造、生物有机金属化学和化学催化中的潜在应用。

In this project funded by the Chemical Structure, Dynamics and Mechanisms B Program of the Chemistry Division, Professor Craig M. Anderson of the Chemistry Program at Bard College investigates the synthesis of transition metal complexes with ligands containing moieties that bond to the metal through multiple coordinating atoms. The optical characteristics and biochemical reactivity of these compounds depend on the ligand architecture, which can be tuned to optimize properties used in potential applications, such as the emission wavelength in organic light emitting diodes (OLEDs). The project adds to the understanding of metal-ligand bonding, offers promise for the development of more efficient and robust OLEDs and anti-cancer agents. A vital component of this work is that it involves the training of undergraduate students and these students gain proficiency in the practice of science in a contemporary chemistry laboratory. They are involved in the dissemination of research results through conference presentations and peer-reviewed journal articles, and thus gain the experience needed in order to continue in their future scientific studies. The project studies metal complexes and cyclometalated complexes that are bonded to ligands with N-heterocyclic carbene and/or cyclometalated benzothiophene moieties or fragments. These complexes have potential applications in acting as catalysts, sensors, artificial photosynthetic devices, and bio-organometallic agents. Specific objectives include: 1. the synthesis and characterization of platinum, iridium, and nickel metal complexes with benzothiophene and N-heterocyclic carbene derived ligands; 2. examination of the photophysical properties and reactivity of the metal complexes; and 3. exploration of potential applications of the newly synthesized compounds in OLED device fabrication, bio-organometallic Chemistry, and chemical catalysis.
