Microenvironment engineering in ortho- and para-dendronized metalloporphyrin-fullerene conjugates involving a trans-2-bisaddition pattern.

A new series of dendronized metalloporphyrin-fullerene conjugates as photosynthetic reaction center mimics was developed in a highly regioselective fashion through tether-controlled synthesis. The microenvironment around the porphyrin core is dependent on the spatial substitution pattern and the nature and generation number of the dendrons, which was proven by cyclic voltammetry.
