摘要: Fourier-transform ion cyclotron resonance (FTICR) mass spectrometric studies have been performed on donor–acceptor and donor–bridge–acceptor fullerene-based systems. Matrix-assisted laser desorption/ionization (MALDI) was used for production; both the positive negative modes were utilized. In addition, collision-induced dissociation (CID) experiments carried out to study movement of charge (electron or hole) upon fragmentation. The are complemented by ab initio theoretical calculations yielding molecular orbital energies electron density distributions. It found that map predicted experimentally observed fragmentation correctly in every case. Both MS may be useful studying these related donor-acceptor systems view their use separation eventually, solar energy production.
