This review focuses on the postfunctionalization of porphyrins and related compounds
through catalytic and stoichiometric organometallic methodologies. The employment of …

Conspectus The properties of polycyclic aromatic hydrocarbons are determined by their
size, shape, and functional groups. Equally important is their curvature, since deviation from …

Accurate identification of carbon‐based metal‐free electrocatalyst (CMFE) activity and
enhancing their catalytic efficiency for O2 conversion is an urgent and challenging task. This …

Expanded carbohelicenes with structures fused to 15-and 17-benzene were successfully
synthesized. Establishing a new synthetic strategy is crucial to realize the development of …

This work describes a synthetic chiral graphene nanoribbon, named supertwistacene 1. It
has four superbenzene (HBC) units linearly fused in a helical manner. The structure of 1, 4.3 …

Curved π-conjugated molecules have attracted considerable interest because of the unique
properties originating from their curved π surface. However, the synthesis of such distorted …

Quadruple helicenes, bearing dithia [6] helicene and [5] helicene substructures, were
prepared by a well-controlled Scholl reaction. The 4-fold helicity provides 9 stereoisomers …

Supramolecular chemistry has received much attention for decades. Macrocyclic
architectures as representative receptors play a vital role in supramolecular chemistry and …

Abstract ortho‐Methyl effects are exploited to tune steric hindrance between side‐chain N,
N′‐diaryls and polycyclic dihydrodibenzo [a, c] phenazine, and in turn control the …

Porphyrin and their versatile metal complexes represent a special class of coordination
compounds possessing unique physical-chemical properties. The achievements in the …
