The Green Box: An Electronically Versatile Perylene Diimide Macrocyclic Host for Fullerenes

The powerful electron accepting ability of fullerenes makes them ubiquitous components in biomimetic donor–acceptor systems that model the intermolecular electron transfer processes of Nature's photosynthetic center. Exploiting perylene diimides (PDIs) as components in cyclic host systems for the noncovalent recognition of fullerenes is unprecedented, in part because archetypal PDIs are also electron deficient, making dyad assembly formation...
