The “special pair” of bacteriochlorophyll molecules in the reaction center of bacterial photosynthesis is immediately recalled to mind by two properties of the title compounds (cf. right): (1) The stable radical cation exhibits strong absorption in the near infrared; (2) the redox potential of this oxidation lies well below that of the corresponding magnesium monotetrapyrrole.
