Metal agents have made incredible strides in preclinical research and clinical applications in
recent years, but their short emission/absorption wavelengths continue to be a barrier to …

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 …

Compared to porphyrin, its isomeric, expanded, and contracted analogues are less well
explored. This contrast is found to be even more drastic in the case of their peripherally …

Triply linked porphyrin arrays, so called porphyrin tapes, are intriguing molecules in terms of
their planar structures, far red‐shifted absorption bands, multi‐charge storage abilities, and …

This feature article focuses on acid catalysis in various redox reactions of not only organic
compounds but also metal complexes, in particular metal‐oxygen complexes via acid …

A family of bandgap-tunable pyrroles structurally related to rylene dyes was computationally
designed and prepared using robust, easily scalable chemistry. These pyrroles show highly …

Porphyrin-based two-dimensional polymers have uniform micropores and close to atom-thin
thicknesses, but they have not been explored for gas separation. Herein we design various …

Norcorrole Ni (II) complexes have recently received considerable attention because they are
readily accessible antiaromatic molecules. Their high stability under ambient conditions and …

The synthesis of organometallic complexes of modified 26π‐conjugated hexaphyrins with
absorption and emission capabilities in the third near‐infrared region (NIR‐III) is described …
