Metal ion assisted derivatization of buckminsterfullerene in the gas phase
- Purdue Univ., West Lafayette, IN (United States)
We report the reactions of CoC[sub 60][sup +] with some simple C[sub 2]-C[sub 4] hydrocarbons and, in particular, the reactions with cyclopropane (c-C[sub 3]H[sub 6]) in which C[sub 60] derivatives are formed. All of the experiments were performed in an Extrel FTMS-2000 Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR-MS) equipped with a 3 T superconducting magnet. C[sub 60] was introduced into the source side of the dual FT-ICR cell using a solids probe at 350[degree]C. The temperature of the ion source was kept at 230[degree]C to maintain a static background C[sub 60] pressure of [approximately] 1.0 x 10[sup [minus]8] Torr. Background argon pressure at [approximately] 5.0 x 10[sup [minus]6] Torr was used as the collision gas for thermalization and for collision-induced dissociation (CID) experiments. CoC[sub 60][sup +] was generated by first forming Co[sup +] by laser desorption of the pure metal target using a Nd:YAG laser and then allowing it to react with background C[sub 60], yielding both the charge transfer product, C[sub 60][sup +], and the condensation product, CoC[sub 60][sup +]. The latter was then isolated using FT-ICR ion ejection techniques and allowed to react with a neutral organic molecule which was introduced into the ion trap via either a leak valve or a pulsed valve. 31 refs., 1 fig.
