✦ Synopsis

We propose a new fullerene growth model with a novel picture for selective isomer formation of higher fullerenes. The model described supposes that the fullerene intermediates, consisting of a 5-and &membered ring network (a cap-like structure), undergo a facile interconversion by a "pentagon migration" transformation. This energy stabilization process dramatically reduces the possible candidates of isomers with fullerene cages. The model also predicts the preferential formation of two specific isomers, D2( 5 )-and Dzd(23)Cs4 with a fraction ratio of 2: 1. This conclusion is in contrast to the recent theoreticai prediction that the D2( 22) isomer with a different fuller&e cage is more stable than the D2( 5 )-Cs+
