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 …

Acid-catalyzed condensation of 3-ethoxymethylenecyclopentene-1-carbaldehyde with a
tripyrrane, followed by oxidation with aqueous ferric chloride solutions, afforded moderate …

The colorimetric cyanide sensing ability of free base porpholactone, a pyrrole-modified
porphyrin in which a porphyrin β, β′-double bond was replaced by a lactone functionality …

Porpholactones are porphyrinoids in which one or more β, β′-bonds of the parent
chromophore were replaced by lactone moieties. Accessible to varying degrees by direct …

Chlorins and bacteriochlorins are reduced porphyrin-type derivatives displaying
characteristic structural, physical, and chemical features. Such features make chlorins and …

Indaphyrins, pyrrole‐modified porphyrins containing a cleaved pyrrole β, β′‐bond and two
annulated indanone moieties, possess unusually broadened and redshifted UV/Vis spectra …
