Abstract

The homoassociation of H(4)TPPF(5)S(3) leads to different J-aggregates depending on whether solutions are shaken (homogenization) or stirred magnetically (square-section flask). Vortex stirring due to the generation of laminar flows decreases lateral diffusion therefore it inhibits cluster-to-cluster aggregation mechanisms.
