This award is made as the starter grant increment of Dr. Lerner's Postdoctoral Fellowship in Chemistry Award in support of his research at Oregon State University. The thrust of Dr. Lerner's research is the synthesis of highly oxidized graphite fluorides by novel chemical routes. The synthesis to be examined will not employ elemental fluorine as an oxidant. Instead, powerful, but convenient, oxidants such as Mn(VII) and Cr(VI) in combination with solutions containing small, readily-intercalated ions such as fluoride or bifluoride will be utilized. These reactions can be carried out under ambient conditions in aqueous acid solvents. A variation will be to employ graphite salts such as those of stable fluorometallate or oxometallate anions rather than graphite as a starting material. The structural, electronic and electrochemical properties of the graphite fluorides will be examined by X-ray diffraction, 4-probe conductivity measurements, vibrational spectroscopy and coulometric reduction.

该奖项是勒纳博士化学博士后奖学金的启动补助金增量，以支持他在俄勒冈州立大学的研究。 Lerner 博士的研究主旨是通过新颖的化学路线合成高度氧化的氟化石墨。 待检查的合成不会使用元素氟作为氧化剂。相反，将使用强大但方便的氧化剂（例如 Mn(VII) 和 Cr(VI)）与含有小且易于嵌入的离子（例如氟化物或氟化氢）的溶液相结合。这些反应可以在环境条件下在含水酸溶剂中进行。一种变化是使用石墨盐，例如稳定的氟金属酸盐或金属氧酸盐阴离子的那些盐，而不是石墨作为起始材料。氟化石墨的结构、电子和电化学性质将通过 X 射线衍射、四探针电导率测量、振动光谱和库仑还原法进行检查。
