Chlorophylls make Earth green, are the central constituents in the engine of photosynthesis,
and not surprisingly have garnered immense attention. A chlorin, the core chromophore of a …

The replacement of one or more pyrrolic building block (s) of a porphyrin by a nonpyrrolic
heterocycle leads to the formation of so-called pyrrole-modified porphyrins (PMPs) …

Chemical modification at the periphery with nitrogen or chalcogens is a highly promising
strategy to diversify the optical, electrochemical, magnetic, and coordination properties of the …

This review summarizes synthetic strategies for the preparation of asymmetric
phthalocyanines and their analogues. Cross-condensation between two phthalonitrile …

In recent years, several synthetic strategies aiming at the peripheral functionalization of
porphyrins were developed. Particularly interesting are those involving the modification of β …

The rational syntheses of meso-tetraaryl-3-oxo-2-oxaporphyrins 5, known as
porpholactones, via MnO4–-mediated oxidations of the corresponding meso-tetraaryl-2, 3 …

We describe an efficient ruthenium‐catalyzed oxidation of the β, β′‐pyrrolic ring on the
porphyrin periphery. Through the conversion of a β, β′‐double bond to a lactone moiety …
