Abstract
This study demonstrated the stabilizing role of a cyclodextrin on Keggin (PW12O40) 3- via hydrogen bonding complex- ation unveiled 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 of POM 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.
