Chemistry within Van Der Waals Cluster of Unsaturated Molecules: Observation ofCationic Polymerization

摘要

We present in this paper the observation of intracluster ion-moleculepolymerization reactions within clusters containing molecules which possess double or triple carbon-carbon bonds. This effect is borne out by the observation of unusual magic numbers in the cluster ion distribution only under expansion conditions which favor the production of large neutral clusters. These magic numbers are rationalized in terms of the production of covalently bonded cyclic molecular ions which terminate the cationic polymerization process.
