title: Purpurinimide-fullerene dyads: introduction of fullerene moiety at various peripheral positions of the purpurinimide system.
abstract: [reaction: see text] Fullerene was regioselectively introduced at various peripheral positions of N-hexyl-purpurinimide for photoinduced electron transfer studies. Remarkably different effects of the position of the fullerene moiety in the formation of atropisomers were observed.
