Abstract
This study demonstrated the stabilizing role of a cyclodextrin on Keggin [PW12O40]3- via hydrogen bonding complexationunveiled by ESI-MS. The distinctive fragmentation pathways of the {PW12}/γ-CD complexes from that of discrete[PW12O40]3- showed that the so-called “weak” non-covalent interactions can effectively change the dissociation chemistry ofPOM in the gas phase. The influence of different types of solvents and organic additives such as γ-CD on the stability of Keggin[PW12O40]3- was also addressed firstly by ESI-MS.
