Heterocyclynes

Wiley J. Youngs和Claire A. Tessier，化学系，阿克伦大学，由无机，生物无机和有机化学计划的支持，用于杂环炔的合成和研究。这些环状聚炔含有硅、锗、铂、钛和其他杂原子，这些杂原子将调节结合口袋的大小和化学性质。该项目还将把杂环炔扩展到含有金属-金属键的络合物、含有刘易斯酸性位点和刘易斯碱性位点的双口袋杂环炔、具有较大口袋或可用作分子镊子的杂环炔以及具有独特材料性质（如液晶性、折射率或非线性光学活性）的杂环炔。杂环炔是超分子化学中的一个重要组成部分。三苯并环三炔的这些类似物具有可以选择性地结合金属离子和其他客体物质的明确限定的口袋。它们也是分子电子学的潜在组成部分。在这一领域接受培训的学生将发展合成，光谱学和晶体学方面的技能。

Wiley J. Youngs and Claire A. Tessier, Department of Chemistry, University of Akron, are supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for the synthesis and study of heterocyclynes. These cyclic polyalkynes contain silicon, germanium, platinum, titanium and other heteroatoms that will tune the size and chemistry of a binding pocket. The project will also extend heterocyclynes to complexes containing metal-metal bonds, dipocket heterocyclynes that contain a Lewis acidic site and a Lewis basic site, heterocyclynes that have larger pockets or can act as molecular tweezers, and heterocyclynes that have unique materials properties such as liquid crystallinity, semiconductivity or non-linear optical activity. Heterocyclynes are a key building block in supramolecular chemistry. These analogs of tribenzocyclotriyne have well-defined pockets that can selectively bind metal ions and other guest species. They are also potential components of molecular electronics. Students trained in this area will develop skill in synthesis, spectroscopy and crystallography.
