MS/MS of incompletely and fully condensed POSS with different substituents - folding and unfolding routes.

摘要

Both pendant groups and structure of the POSS cages were found to greatly influence their MS/MS pathways. While a fully condensed structure is able to unfold to produce a linear copolymeric skeleton as main dissociating species, incompletely condensed structures undergo a folding mechanism - the folded structure being detected as ion or released as neutral.
