Electron transfer (ET) reaction in biological systems plays an important role in respiratory oxidative phosphorylation and photosynthesis. In the respiratory system, two electron carriers, ubiquinone and cytochrome c, control the overall reaction of ET process via specific interaction with membrane-bound oxidoreductases. The present review describes two topics of the synthetic modeling of noncovalently linked donor-acceptor systems using porphyrin unit; (1) preparation and characterization of ubiquinone receptors by use of a functional porphyrin, which shows the photoinduced ET reaction within the porphyrin-quinone complex formed by hydrogen bonding interaction. (2) construction of binding sites on the surface of myoglobin and mimicking of protein-protein complexation. In this review, I wish to report the suitable model systems to evaluate the intermolecular ET of the electron carriers via molecular recognition.
