A new type of acceptor–donor2 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 photocurrent generation that surpasses the device using the corresponding zinc porphyrin.
