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) …

Two-dimensionally extended, polycyclic heteroaromatic molecules (heterocyclic
nanographenes) are a highly versatile class of organic materials, applicable as functional …

Core alteration, affording heteroporphyrinoids and carbaporphyrinoids, allows for the
exploration of porphyrin-like or porphyrin-unlike coordination chemistry. Such a strategy has …

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 …

Incorporation of planarized heteroatom (s) onto the porphyrin periphery is an effective
approach to create porphyrin-based functional materials. In the last three decades, such an …

meso-Tetrahexylporphyrin was converted to its corresponding 7, 8-dihydroxychlorin using
an osmium tetroxide-mediated dihydroxylation strategy. Its diol moiety was shown to be able …

The conversion of meso-aryl-porphyrins/chlorins to porphyrinoids containing nonpyrrolic
heterocycles (so-called pyrrole-modified porphyrins, PMPs) along an approach we dubbed …

As a result of their large aromatic π‐systems, porphyrins, hydroporphyrins, and their metal
complexes display a rich reversible redox chemistry that is frequently studied by …
