Modeling intermolecular interactions of complex non‐covalent structures is important in
many areas of chemistry. To facilitate the generation of reasonable dimer, oligomer, and …

Herein, we report robust π-conjugated radical cations resulting from the oxidation of
hexabenzoperylene (HBP) derivatives, HBP-B and HBP-H, which have butyl and hexyl …

Synthetic strategies to access high‐valent iridium complexes usually require use of π
donating ligands bearing electronegative atoms (eg amide or oxide) or σ donating …

Cyclophane‐type dications with two units of xanthylium were designed, with the expectation
that intramolecular interaction between cation units could induce changes in absorption and …

Two tetraarylanthraquinodimethane (Ar4AQD) derivatives having two different aryl groups
(aminophenyl and methoxyphenyl) were prepared by sequential dibromomethylation and …

Orthogonal and twisted dimers of pyrrole-fused pentaazapolycyclic hydrocarbons
(pentaazacoronene analogs) were synthesized, linked either directly or by phenylenes …

Cationic molecules have distinct properties that differ from those of electronically neutral
molecules. They have been extensively studied and utilized as reaction intermediates …

In recent years, near‐infrared (NIR) dyes, exhibiting absorption in the NIR region (750‐2500
nm), have been applied to various optical applications such as security marking …
