This work provides an overview of the recent advances in the field of two-photon absorbing
chromophores active in the short-wavelength infrared (SWIR) spectral range. Herein 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 …

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 …

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 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 …

The non-innocent ligand nature of porphyrins was observed for compound I in enzymatic
cycles of cytochrome P450. Such porphyrin radicals were first regarded as reactive …

The preparation of novel stable radical systems that survive and may be manipulated under
harsh conditions is essential for their practical applications, such as energy storage and …

The way in which photons travel through biological tissues and subsequently become
scattered or absorbed is a key limitation for traditional optical medical imaging techniques …

Expanded porphyrins are a class of porphyirinoid macrocycles possessing more than four
pyrrole/other heterocyclic rings and multiple meso-carbon bridges in their conjugated …
