Abstract: The evolution of the morphological properties of solutions of endohedral metallofullerene La@C$_{82}$ in $N,N$-dimetilformamide in the presence of a coagulant was studied by dynamic and static light scattering methods. Based on the experimental results, the time evolution of the light scattering intensity, and the hydrodynamic radius of endohedral metallofullerene clusters, their association constants and aggregation rates are determined. Based on the analysis of the angular dependences of light scattering in solutions of endohedral metallofullerenes, the fractal dimension of La@C$_{82}$ clusters in solutions of various concentrations at the initial and final stages of their aggregation was estimated.

Keywords: endohedral metallofullerenes, aggregation, dynamic and static light scattering, fractal clusters.
