Proximate moieties, through-space

Up front, a general comment seemed necessary Photophysical studies indicate that, when structurally possible, dyads adopt conformations in which the porphyrin and fullerene moieties are in close proximity, thus facilitating through-space interactions of photoexcited porphyrins with the fullerenes. A similar conclusion stems from a recent work that demonstrates impressively weak ligand interactions between Cso and a hard metal such as iron(III) in an iron(III)tetraphenylporphyrin r-radical cation (FeP +) [352],...
