Synthesis and characterization of several 26 pi core-modified hexaphyrins are reported. The synthetic methodology involved a well-known acid-catalyzed MacDonald-type condensation reaction of the required tripyrrane with ...

Acid-catalyzed condensation of furan and pentafluorobenzaldehyde yielded conjugated macrocycles with six and eight furan rings. They represent systems similar to annulenes with 30 d and 40 d electrons. From their structural ...

The synthesis and structural characterization of the first examples of planar aromatic core modified [34]octaphyrins(1.1.0.1.1.0.0.0) with three different heteroatoms containing a quaterthiophene subunit are reported.

The syntheses and spectral and structural characterization of hitherto unknown p-benzene incorporated normal, expanded, strapped and N-confused calixbenzophyrins are achieved; altogether five new macrocycles from a single ...
