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 …

Conspectus Naturally occurring porphyrins and hydroporphyrins vary with respect to their
ring substituents and oxidation states, but their tetrapyrrolic frameworks remain fully …

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