Chlorinated fullerenes which have been prepared by a variety of different synthetic methods have been studied by means of direct laser desorption/ionisation (LDI), matrix-assisted laser desorption/ionisation (MALDI) and desorption electron ionisation (DEI) mass spectrometry. The aim of this investigation has been the elucidation of the unusual signal sequence observed in earlier positive-ion MALDI experiments, which featured a spacing of 77 Da between the signals of fullerene-containing ions. Circumstantial evidence has been provided, which strongly indicates that the 77 Da correspond to a C6H5 (phenyl) ligand. The findings reveal that phenylated by-products that result from the use of benzene during synthesis may be of strong influence on the physico-chemical characterisation of chlorinated C-60.
