A series of directly linked metalloporphyrin–arylimidazole heterodyads (, , and ) with an arylimidazole unit at the meso‐ or β‐pyrrolic position of the porphyrin were synthesized via Debus–Radziszewsk reaction. Introduction of a copper ion into the porphyrin contributed significantly to the overall stability of the heterodyads. The absorption spectra indicated that the basic electronic characteristics of both individual units (i.e., metalloporphyrin and arylimidazole) were retained in the heterodyads. In addition, strong fluorescence quenching was observed in the case of the heterodyads containing copper(II) porphyrin. Cyclic voltammetric studies revealed that the heterodyads were more difficult to oxidize compared with the pristine metalloporphyrins.
