This award by the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Guy Bertrand, University of California at Riverside, on the synthesis and characterization of boron-phosphorus compounds with unusual bonding and electronic states. This class of compounds consist of a four-membered ring with alternating boron and phosphorus atoms. By judicious substitution on the boron and phosphorus atoms, the electronic ground state can be "tuned" along a continuum from a sigma-bonded system to singlet or triplet diradicals. The structure, bonding and reactivity of these unusual boron-phosphorus molecules will be studied. Related classes of compounds such as aluminum-phosphorus or aluminum-nitrogen systems will also be explored. Fundamental questions of bonding and electronic structure will be addresssed by this study. Possible long-term applications include polymers with unique magnetic properties. This research will also promote collaborative research and the exchange of undergraduates, graduates and postdoctoral fellows between UC Riverside and several French universities.

该奖项由无机、生物无机和有机金属化学项目颁发，支持加州大学河滨分校 Guy Bertrand 的研究，该研究涉及具有不寻常键合和电子态的硼磷化合物的合成和表征。这类化合物由硼和磷原子交替的四元环组成。通过对硼和磷原子进行明智的取代，电子基态可以沿着从西格玛键合系统到单线态或三线态双自由基的连续体“调整”。我们将研究这些不寻常的硼磷分子的结构、键合和反应性。还将探索相关类别的化合物，例如铝-磷或铝-氮系统。本研究将解决键合和电子结构的基本问题。可能的长期应用包括具有独特磁性的聚合物。这项研究还将促进加州大学河滨分校和几所法国大学之间的合作研究以及本科生、研究生和博士后的交流。
