M. Frederick Hawthorne, Department of Chemistry and Biochemistry, University of California Los Angeles, is continuing his research into functionalized carboranes with the support of the Inorganic, Bioinorganic and Organometallic Chemistry Program. Methylation of carboranes leads to octamethyl derivatives. These methyl groups will be functionalized to give "camoflagued carboranes" with desirable properties. The methylated carboranes will be studied as ligands for electron-deficient transition metals analogous to pentamethylcyclopentadienyl. Direct hydroxylation of boranes provides route into other new classes of boron clusters with tunable electronic properties.Carboranes and boranes have interesting structures and have led to new insights into bonding. The functionalized clusters studied in this grant may have applications in water-soluble catalysis, drug delivery, and molecular electronics. The project incorporates synthesis, characterization and materials applications, making it an excellent project for training students.

M.洛杉矶加州大学化学与生物化学系的Frederick霍桑在无机、生物无机和有机化学项目的支持下，正在继续他对官能化碳硼烷的研究。碳硼烷的甲基化产生八甲基衍生物。这些甲基基团将被官能化以得到具有所需性质的“改性碳硼烷”。甲基化碳硼烷将被研究作为缺电子过渡金属类似于五甲基碳硼烷的配体。 硼烷的直接羟基化反应提供了一条通向其他新的具有可调电子性质的硼簇合物的途径。碳硼烷和硼烷具有有趣的结构，并导致了对成键的新认识。本研究所研究的功能化团簇可能在水溶性催化、药物输送和分子电子学方面有应用。该项目结合了合成，表征和材料应用，使其成为培训学生的优秀项目。
