Abstract
Stable complexes of oligomers of polyether (oxyethylated glycerol derivatives) with a chlorine anion have first been registered in negative-ion electrospray ionization mass spectra. The results of molecular dynamics simulation demonstrate that the stabilization of such complexes in the gas phase can be due to the formation of a quasicyclic structure of the polymer chain around the chlorine anion and its coordination by CH2- and OH- groups of the oligomer. This structure is inverted towards the known quasicyclic structure of polyethers, in which metal cations are coordinated by oxygen atoms of ether groups.
