U.S.-Brazil Cooperative Research in the Synthesis and Structures of Tellurium and Selenium Compounds

该奖项支持博士的参与。德州农工大学的拉尔夫·津加罗和爱德华·迈耶斯与约翰博士合作进行了一项研究。巴西圣保罗大学的N. Petragnani和J. Comasseto说。他们共同努力的重点是对两组合成的碲（Te）和硒（Se）新化合物的理化性质进行表征。两个小组都在有机金属化学这一不同寻常的领域建立了良好的项目，他们之前的合作非常富有成效。特别是，巴西集团在合成Se/Te有机金属材料和开发各种此类材料的一般合成路线方面具有专业知识。美国团队除了在合成方面的经验外，还拥有光谱表征和新化合物单晶x射线结构测定的专业知识和最先进的仪器。这种相互补充的专门知识专门用于共同感兴趣的领域，在过去产生了非常富有成效的合作，可以预期这种合作将继续下去。有机金属化学已成为一个日益重要的领域，因为这类化合物的潜在用途作为电子材料。这次合作的主要研究者为我们对Se和Te有机金属化合物的了解做出了重大贡献，这对于开发制备新型电子材料的新方法应该是重要的。

This award supports the participation of Drs. Ralph Zingaro and Edward Meyers of Texas A&M University in collaborative research with Drs. N. Petragnani and J. Comasseto of the University of Sao Paulo, Brazil. The focus of their joint effort is the characterization of physico- chemical properties of new tellurium (Te) and selenium (Se) compounds which have been synthesized by the two groups. Both groups have well established programs in this unusual area of organometallic chemistry, and their prior collaboration has been very productive. In particular, the Brazilian group has expertise in synthesis of Se/Te organometallics and the development of general synthetic routes for various classes of such materials. The U.S. group, in addition to their experience in synthesis, has expertise and state of the art instrumentation for spectroscopic characterization and single crystal x-ray structural determination of new compounds. This complementary expertise devoted to an area of mutual interest has resulted in very fruitful collaboration in the past which can be expected to continue. Organometallic chemistry has become an increasingly important field because of the potential uses of such compounds as electronic materials. The principle investigators in this collaboration have contributed substantially to our knowledge of Se and Te organometallic compounds, which should prove to be important for the development of new methods for the preparation of novel electronic materials.
