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.

无机，生物无机和有机化学计划的这一奖项支持德克萨斯理工大学的Dominick J.Casadonte教授的研究，重点是包含1，10-菲咯啉（phen）和2，9-二甲基-1，10-菲咯啉（dmp）的局部分子组装体的光化学和光物理学，这些分子组装体具有由（3，8），（4，7）和（5）取代提供的不同维度，6）菲咯啉环系上的位置。 长期目标包括了解光活性和光电分子系统的空间要求。 基本的光子和电子的研究将进行一系列的铜（I）低聚物和聚合物组件包含取代的二亚胺配体通过丙烯酸酯或乙炔基键结合在一起。所提出的聚-（Cu（I）（dmp- 5-丙烯酸酯）2和聚-（Cu（I）（dmp-5-丙烯酸酯）（PPH 3）2化合物将以σ键合的方式连接在每个菲咯啉配体的5位。 这些分子聚集体的MLCT带的光激发将导致整个网络的电荷分离。 Cu（I）聚乙炔菲咯啉材料将在整个晶格中完全π-共辄。MLCT带的激发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。学生将不仅开发合成和光化学方面的考虑，但也将积极参与西部农村和贫困地区的前沿推广活动，通过开发光，光学，光化学和电力方面的教育模块，这些模块将发布在YouTube，iTunes U和PI的网站上。
