Porphyrins feature prominently in nature, be it as enzymatic cofactors, electron and exciton
shuffles, as photoactive dyes, or as signaling substances. Their involvement in the …

Since the discovery of its facile synthesis in 2001, meso-aryl-substituted expanded
porphyrins have been developed as a new class of azaannulenes in light of their facile …

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

Confusion is a novel concept of isomerism in porphyrin chemistry, delivering a steady
stream of new chemistry since the discovery of N-confused porphyrin, a porphyrin mutant, in …

Metal ions and anions play important roles in many industrial and biochemical processes,
and thus it is highly desired to detect them in the relevant systems. Small organic molecule …

The chemistry of expanded porphyrins, which are higher homologues of porphyrins, has
been intensively explored for the last three decades. Expanded porphyrins exhibit …

Organometallic CuIII species have been invoked in many copper-catalyzed reactions, but
until recently, experimental evidences were lacking. The advent of new spectroscopic …

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) …

Following immediately after the serendipitous discovery of N-confused porphyrins,
remarkably diverse carbaporphyrinoid systems have been synthesized and investigated. By …

meso-Aryl-substituted expanded porphyrins that are porphyrin homologues consisting of
more than five pyrrolic units are a nice platform to realize diverse aromatic and antiaromatic …
