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 …

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 …

The development of multifunctional agents for simultaneous tumor targeting and near
infrared (NIR) fluorescence imaging is expected to have significant impact on future …

The importance of long wavelength and near-infrared (NIR) imaging has dramatically
increased due to the desire to perform whole animal and deep tissue imaging. The adoption …

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

Expanded porphyrins are synthetic analogues of the porphyrins, and differ from these and
other naturally occurring tetrapyrrolic macrocycles by containing a larger central core with a …

This review underscores the conformational flexibility of porphyrinoids, a unique class of
functional molecules, starting from the smallest triphyrins (1.1. 1) via [18] porphyrins (1.1 …

The aromatic character of porphyrins, which has significant chemical and biological
consequences, can be substantially altered by judicious modifications of the parent ring …

The use of cyclic polyene perimeter-model approaches, such as Gouterman's four-orbital
model and Michl's perimeter model, to analyze trends in the electronic structures and optical …

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