英文摘要: Al+(C2H4)(n) clusters were produced by reaction of laser ablated Al+ ions with ethene molecules seeded in a pulsed molecular beam, and detected with a reflectron time-of-flight mass spectrometer. The mass spectrum shows that an Al+ ion can combine with at least eight ethene molecules to form Al+(C2H4)(n) clusters. Based on the photodissociation experiments and ab initio calculations, we suggest that an Al+ ion can strongly interact with one or two C atoms to form Al-C sigma-bonds and trigger addition reaction of ethene molecules to develop chain or ring structures. The interaction of Al+ ion with ethene is different from the interaction between V+ ion and ethene molecules reported previously (Int. J. Mass. Spectrom. 295 (2010)36), wherein a V+ ion can only combine with no more than four ethene molecules at similar experimental conditions and causes little change in the structures of the ethene molecules.
