Impact/Purpose:
To report investigations into the development of mass spectrometric ionization methods for fullerenes and fullerene derivatives.
Description:
Currently investigations into the environmental behavior of fullerenes and fullerene derivatives is hampered by the lack of well characterized standards and by the lack of readily available quantitative analytical methods. Reported herein are investigations into the utility of matrix assisted laser desorption ionization, electrospray ionization, atmospheric pressure chemical ionization, fast atom bombardment, and atmospheric solids analysis probe (ASAP) for the ionization and analysis of fullerenes and fullerene derivatives by mass spectrometry. Most interestingly, ASAP analysis of aqueous fullerene aggregates generated by extended stirring in water produced ions corresponding to C60OxHy with x and y each being less than 7. This is the first reported observation of the functionalization of C60 upon extended stirring in water. Additionally, analysis of hydroxylated fullerene, C60 OH16-24 by ASAP or any other of the above mentioned ionization techniques only produced ions for C60 and no ions diagnostic of the hydroxylated species.
