Photostability of a dyad of magnesium porphyrin and fullerene and its application to photocurrent conversion

A new type of acceptor-donor(2) dyad system containing two magnesium porphyrin molecules and a fullerene molecule is much more stable than the magnesium porphyrin itself. When it is fabricated into a binary system using imidazole carboxylic acid as a linker to indium tin oxide, the molecule effects efficient photo-current generation that surpasses the device using the corresponding zinc porphyrin.
