Chemically mixed molecular crystals show, similarly to isotopically mixed crystals, percolation phenomena for triplet-excitation energy transport. However, because of strong guest-host interaction, energy disorder in the form of induced energy funnels masks the fractal nature of the percolating guest clusters. The assumption of a spectral dimension of d s = j for percolation at the critical concentration needs in the present case the introduction of an additional waiting-time distribution for a random-walk process.
