N2 - Fluorinated graphite intercalation compounds (FGICs) with acetonitrile C2Fx-yCH3CN (x = 0.92, 0.69, and 0.49) have been synthesized using a gaseous mixture of BrF3 and Br-2 at room temperature and subsequent replacement of the reaction medium components on acetonitrile by isopiestic method. The change in functional composition and electronic structure of FGICs under annealing at 250-260 degrees C was studied by infrared, X-ray photoelectron, and near-edge X-ray absorption fine structure spectroscopy (NEXAFS) methods. Analysis of the data revealed interaction of acetonitrile with a C2Fx matrix. The X-ray spectra detected formation of new nitrogen species attributed to two-coordinated and mono hydrogenated three-coordinated atoms. Mechanism of nitrogen incorporation in the fluorinated graphene layers was proposed.[GRAPHICS]Schematic structure of graphite fluoride C2Fx intercalated with acetonitrile and NEXAFS N K-edge spectrum of C2F0.69 center dot(0).137CH(3)CN before and after annealing at 250 degrees C.
