Production and Analysis of Metallocarbohedrene Containing Soot
Abstract
Since the initial discovery of metallocarbohedrenes (Met-Cars) by our group, as both neutrals and ions, there has been growing interest in these molecular clusters. In order to experimentally determine their structure, Met-Cars must be analyzed in the solid state. Recently it has been shown that Met-Cars can be formed via arc-discharge and direct laser vaporization of metal carbides. Soot produced from laser vaporization of various metal carbides (TiC, ZrC, VC, and NbC) in an argon atmosphere are extracted using various solvents and analyzed. A new instrument has been designed where we can perform laser vaporization on these metal carbides (at various conditions) and collect the vaporized material on different substrates. The substrate can then be translated into the next chamber where the deposited material is analyzed via laser desorption time-of-flight mass spectrometry (LD TOF-MS). We will present analysis of these metal-carbon deposits using various techniques (including LD TOF-MS, NMR, STM, etc.).
