Synthesis and Spectroscopic Studies of Copper (I) Phenanthroline Molecular Assemblies

这个无机、生物无机和有机金属化学项目的奖项支持了德克萨斯理工大学的Dominick J.Casadonte教授对含有1,10-菲罗啉（phen）和2,9-二甲基-1,10-菲罗啉（dmp）的局部分子组装体的光化学和光物理学的研究，这些分子组装体在菲罗啉环系统的（3,8）、（4,7）和（5,6）位置上的取代提供了不同的维度。长期目标包括了解光活性和光电子分子系统的空间要求。基础光子和电子研究将对一系列含有取代二亚胺配体通过丙烯酸酯或乙基键结合在一起的Cu(I)低聚物和聚合物进行。所提出的聚(Cu(I)（dmp-5-丙烯酸酯）2和聚(Cu(I)（dmp-5-丙烯酸酯）（PPH3）2化合物将以sigma键方式连接在每个菲罗啉配体的5位上。光激发这些分子聚集体的MLCT带将导致整个网络中的电荷分离。Cu(I)聚乙基邻菲罗啉材料将在整个晶格中完全π共轭。激发MLCT带将产生通过聚合物或低聚物链的电子流。该研究旨在为分子电子电路元件的制造奠定基础。学生们不仅将发展对合成和光化学方面的考虑，而且还将通过开发光、光学、光化学和电学方面的教育模块，积极参与到西方农村和贫困地区的前沿推广活动中，这些模块将发布在YouTube、iTunesU和PI的网站上。

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports Professor Dominick J.Casadonte at Texas Tech University for research focused on the photochemistry and photophysics of localized molecular assemblies containing 1,10-phenanthroline (phen) and 2,9-dimethyl-1,10-phenanthroline (dmp) with varying dimensionalities afforded by substitution at the (3,8), (4,7), and (5,6) positions on the phenanthroline ring system. The long-term goal involves an understanding of the spatial requirements for photoactive and optoelectronic molecular systems. Fundamental photonic and electronic studies will be conducted on a series of Cu(I) oligomeric and polymeric assemblies containing substituted diimine ligands bound together via acrylate or ethynyl linkages. The proposed poly-(Cu(I)(dmp- 5-acrylate)2 and poly-(Cu(I)(dmp-5-acrylate)(PPH3)2 compounds will be linked at the 5 position of each of the phenanthroline ligands in a sigma-bonded fashion. Photoexcitation of the MLCT bands of these molecular aggregates will lead to charge separation throughout the network. The Cu(I) polyacetylenic phenanthroline materials will be fully pi-conjugated throughout the lattice. Excitation of the MLCT bands will produce electron flow through the polymer or oligmer chains. The research aims to set the stage for the fabrication of molecular electronic circuit elements. Students will not only develop a consideration of aspects of synthetic and photochemistry, but will also be actively involved in cutting-edge outreach in rural and disadvantaged areas in the West through the development of education modules in light, optics, photochemistry, and electricity that will be posted on YouTube, iTunesU, and the PI's website.
