(Chemical Equation Presented) Running rings around mercuric ions: A [26]hexaphyrin(, comprising an α,α′-bipyrrole unit and four pyrrolic and five pentafluorophenyl rings, was prepared and characterized by X-ray crystallography (see picture; N blue, F green, C black). The expanded porphyrin displays near-infrared luminescence above 900 nm and may serve as a highly sensitive and selective chemodosimeter for Hg2+ ions. KGaA.
