Metallophilic Interactions in Closed-Shell Metal-Metal Bonded Luminescent Systems and Their Tunability for Excited State Energy Transfer

霍华德·帕特森，缅因大学，由无机、生物无机和有机金属化学项目资助，从事金属-金属键合准分子和络合物的光化学研究。在溶液或固体状态下，双氰酸盐(I)和双氰酸盐(I)离子会发生低聚反应。低聚物表现出复杂的光化学反应，包括由亲金相互作用引起的发光。这些系统可以通过掺杂或添加各种供体离子来调谐超过18,000个波数。该研究项目将详细研究寿命和时间分辨研究、拉曼散射和红外振动分析、x射线和中子衍射结构研究以及理论分析。该研究将为亲金属相互作用和无机发光复合物的研究提供新的思路。具有这种不寻常光化学行为的无机配合物可用于构建固态光子系统。也有应用在传感器和临床分析使用发光检测。学生将接受各种仪器和技术的培训，这些仪器和技术将在纳米科学和工程中发挥重要作用。

Howard Patterson, University of Maine, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for photochemical studies of metal-metal bonded excimers and exciplexes. In solution or in the solid state, dicyanoaurate(I) and dicyanoargentate(I) ions oligomerize. The oligomers show complex photochemistry, including luminescence caused by metallophilic interactions. These systems can be tuned over 18,000 wavenumbers by doping or by adding various donor ions. This research project will look in detail at lifetime and time-resolved studies, vibrational analysis by Raman scattering and infrared, structural studies by x-ray and neutron diffraction, and theoretical analyses. The research will provide insight into metallophilic interactions and inorganic luminescent exciplexes.Inorganic complexes with this unusual photochemical behavior can be used to build solid state photonic systems. There are also applications in sensors and clinical assays using luminescence detection. Students will be trained in a variety of instruments and techniques that will be important in nanoscale science and engineering.
