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.

霍华德帕特森，缅因州大学，是由无机，生物无机和有机化学计划的金属-金属键合准分子和激基复合物的光化学研究的支持。在溶液或固态中，二氰基金酸根（I）和二氰基银酸根（I）离子低聚。低聚物显示出复杂的光化学，包括由亲金属相互作用引起的发光。这些系统可以通过掺杂或添加各种施主离子来调谐超过18，000个波数。该研究项目将详细研究寿命和时间分辨研究、通过拉曼散射和红外线进行的振动分析、通过X射线和中子衍射进行的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激基复合物的研究提供新的视角，具有这种不寻常光化学行为的无机复合物可用于构建固态光子系统。还存在使用发光检测的传感器和临床测定中的应用。学生将接受各种仪器和技术的培训，这些仪器和技术在纳米科学和工程中非常重要。
