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

这一无机化学、生物无机化学和金属有机化学奖支持德克萨斯理工大学的Dominick J.Casadonte教授，他的研究重点是通过取代邻菲咯啉环系上的(3，8)、(4，7)和(5，6)位提供的具有不同维度的1，10-菲咯啉(Phen)和2，9-二甲基-1，10-菲咯啉(DMP)的局域分子组件的光化学和光物理。长期目标包括了解光活性和光电子分子系统的空间要求。基本的光子和电子研究将对一系列铜(I)齐聚物和聚合物组合物进行，这些组装体含有取代的二亚胺配体，通过丙烯酸酯或乙炔基键连接在一起。所合成的聚(铜(I)(DMP-5-丙烯酸酯)2和聚(铜(I)(DMP-5-丙烯酸酯)(PPH3)2)化合物将以Sigma键的形式连接在每个邻菲罗啉配体的5位。这些分子聚集体的MLCT带的光激发将导致整个网络中的电荷分离。铜(I)聚乙酰基邻菲咯啉材料将在整个晶格中完全pi共轭。MLCT带的激发将产生通过聚合物或低聚物链的电子流动。这项研究的目的是为分子电子电路元件的制造奠定基础。学生不仅将发展对合成和光化学方面的思考，还将通过开发将在YouTube、iTunesU和PI的网站上发布的光、光学、光化学和电学的教育模块，积极参与到西部农村和贫困地区的前沿推广活动中。

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.
