9412387 Tessier University of Akron阿克伦大学化学系的Claire Tessier博士得到了无机、生物无机和有机化学计划的支持，用于制备主族和过渡金属杂环炔。环炔配体是环状聚炔。本研究的第一个目标是合成十一元环中含有三个炔、两个苯基和一个杂原子的环炔化合物。包含在环中的杂原子包括主金属和过渡金属。将研究这些杂环炔与其他过渡金属的相互作用，特别是关于其中过渡金属在配体的空腔内络合的络合物的形成。腔和环的几何约束可以迫使环中的金属与腔中的金属之间的金属-金属键合相互作用。 含有两种金属的不对称化合物正被开发用于激活一氧化碳等小分子和作为非线性光学材料。本研究将通过形成含金属的原子环来形成一类新的此类配合物，该环包含第二金属可以进入的空腔。两种金属 将足够接近，相互作用，这可能会产生新的系统，能够激活小分子，并产生独特的光学特性。

9412387 Tessier University of Akron Dr. Claire Tessier, Chemistry Department, University of Akron, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program for the preparation of main group and transition metal heterocyclynes. Cyclyne ligands are cyclic polyalkynes. The first goal of the research is the synthesis of cyclynes with three alkynes, two phenyl groups and a heteroatom in an 11 membered ring. The heteroatoms to be included in the ring include main and transition metals. The interaction of these heterocyclynes with further transition metals will be investigated, particularly in regard to the formation of complexes in which a transition metal is complexed within the cavity of the ligand. The geometric constraints of the cavity and ring may force a metal-metal bonding interaction between metals in the ring and those in the cavity. Unsymmetrical compounds which contain two metals are being exploited to activate small molecules like carbon monoxide and as non-linear optical materials. This study will form a new class of such complexes by forming a metal containing ring of atoms which contains a cavity which a second metal may enter. The two metals will be close enough to interact with each other, and this may yield new systems capable of activating small molecules and give rise to unique optical properties.
