With the support of the Chemical Synthesis Program of the Chemistry Division, Professor François Gabbaï of the Chemistry Department at Texas A&M University, will investigate novel Lewis acids based on antimony. The first class of compounds targeted in this project are cationic antimony(V) species (or stibonium ions) to be used in water for the detection of potentially toxic anions including fluoride and cyanide. These stibonium ions will be incorporated in conjugated and emissive frameworks to afford a family of compounds that will respond to the presence of the anions via distinct photophysical changes. The second class will be halogenated, electron-deficient organostiboranes which will be designed to rival, if not exceed, the properties of perfluorinated organoboranes. Unlike their boron analogs, these new organoelement Lewis acids should be resistant to oxidative conditions and will be used to study the complexation of reactive oxidizing anions such as peroxide and hypochlorite. In addition, this award will contribute to the education of a diverse group of undergraduate and graduate students, and allow Professor Gabbaï to maintain his involvement in various services and outreach activities.From a broader perspective, this project will have an impact on two main areas. The first area deals with the detection of anions such as fluoride and cyanide, which can sometimes be found at toxic levels in drinking water. The second important area that this project will impact concerns the chemistry of high energy molecules that are intermediates in important energy storage reactions. The advances made in this project will be mostly fundamental but may contribute to the health of our society or to the development of new energy storage technologies.

在化学系化学合成项目的支持下，德克萨斯农工大学化学系的 François Gabbaï 教授将研究基于锑的新型路易斯酸。该项目的第一类目标化合物是阳离子锑（V）物质。 （或锑离子）用于水中检测潜在有毒阴离子，包括氟化物和氰化物。这些锑离子将掺入共轭和阴离子中。提供一系列化合物的发射框架，这些化合物将通过独特的光物理变化对阴离子的存在做出反应。第二类是卤化的缺电子有机硼烷，其设计旨在与全氟化有机硼烷的性能相媲美（如果不是超过的话）。与它们的硼类似物不同，这些新的有机元素路易斯酸应该能够抵抗氧化条件，并将用于研究反应性氧化阴离子（例如过氧化物和阴离子）的络合。此外，该奖项将有助于不同群体的本科生和研究生的教育，并使加拜教授能够继续参与各种服务外展和活动。从更广泛的角度来看，该项目将对两个人产生影响。第一个领域涉及氟化物和氰化物等阴离子的检测，这些阴离子有时会在饮用水中达到有毒水平。该项目将影响的第二个重要领域涉及作为中间体的高能分子的化学。重要的储能反应取得的进展。该项目主要是基础性的，但可能有助于我们社会的健康或新能源存储技术的发展。
