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 …

Sensing of metal ions and anions is of great importance because of their widespread
distribution in environmental systems and biological processes. Colorimetric and fluorescent …

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

Organic light-emitting diodes (OLEDs) produced from metal complexes play an important
role in modern electroluminescent devices. While OLEDs are being used in display various …

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 heteroatom-containing porphyrin analogues or core-modified porphyrins that resulted
from the replacement of one or two pyrrole rings with other five-membered heterocycles …

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) …

The world of modified porphyrins changed forever when an N-confused porphyrin (NCP), a
porphyrin isomer, was first published in 1994. The replacement of one inner nitrogen with a …

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 …
