Short-distance porphyrin heterodimers may be used for very efficient titrations in water measuring fluorescence quenching in 1:1 molecular complexes between diamagnetic and paramagnetic metalloporphyrins. Radical dimers produce strong charge transfer bands near 900 nm. Long-distance heterodimers, e.g. chlorophyll-ubiquinone, play a central role in the charge separation process of biological photosynthesis. Attempts to model such dimers in form-stable nanowells are discussed and compared with corresponding molecular complexes and covalent redox systems. Heterodimers may, of course, not only be made of two porphyrins. Other acceptor molecules, which fit exactly in the nanowells, e.g. large quinones may also be applied.
