Abstract

Theoretical models for describing the kinetics of fullerene cluster growth in C 60 solutions in N-methyl-2-pyrrolidone (NMP) are presented. First, a detailed review of current state of experimental investigation of C 60/NMP is given. The relation between C 60-NMP complex formation, cluster growth and their impact on solvatochromism is discussed. Next, a theoretical approach for description of cluster growth, based on kinetic equations of segregation, is proposed. Two modifications of basic approach are given. First one treats cluster growth in a supersaturated solution of C 60, where new complex formation eventually limits growth of aggregates. In the second model a two-step process of cluster growth is considered: complex formation and cluster growth. The solution of C 60-NMP complexes is supersaturated, while initial, "free" C 60 does not aggregate. For each model a procedure for obtaining parameters is proposed and the parameter values are estimated.
