Chemistry of Organic Sulphur, Selenium, and Tellurium Compounds

该研究项目得到了有机合成项目的支持。将研究含硫、硒和碲化合物的化学方面，这些化学方面有可能对有机金属和光学传感器等不同领域产生影响。有机酒精化学的研究将着重于以下几个方面：1 .有机硫化学将研究很少被探索的硫代羰基化合物的化学类型（例如，硫代醌、硫代酸酐）。其他可能是pi给体的硫杂环（例如，四噻吩衍生物，多噻吩等）或LB膜候选物也将成为研究对象。2. 有机硒化学将重点关注新的有机硒试剂、新的含硒给体和硒羰基衍生物。3. 有机碲化学新的含碲TTF及其葡萄状TTF衍生物将被合成。将尝试合成众所周知的1,2,3-噻二唑的碲类似物。研究新的含碲官能团的化学性质。

This research program is being supported by the Organic Synthesis Program. Aspects of the chemistry of compounds containing sulphur, selenium and tellurium will be pursued which have the potential to impact on a diverse number of areas such as organic metals and optical sensors. The investigation in organochalcogen chemistry will emphasize the following areas: l. Organosulfur Chemistry The chemistry of little explored types of thiocarbonyl compounds will be studied (e.g., thioquinones, thionoanhydrides). Other sulfur heterocycles which are potential pi donors (e.g., tetrathiafulvalene derivatives, polythiophenes, etc.) or LB film candidates will also be objects of investigation. 2. Organoselenium Chemistry Attention will be focussed on new organoselenium reagents, new selenium-containing pi donors, and selenocarbonyl derivatives. 3. Organotellurium Chemistry New tellurium-containing TTF and vinylogous TTF derivatives will be synthesized. Attempts will be made to synthesize tellurium analogs of the well known 1,2,3-thiadiazoles. The chemistry of new tellurium-containing functional groups will be investigated.
