Conjugated covalent organic cages (cCOCs) are three-dimensional (3D) giant molecules
characterized by π-conjugated skeletons and interconnected multi-windows. Their …

A nanographene-fused expanded carbaporphyrin (5) and its BF2 complex (6) were
synthesized. Single-crystal X-ray structures revealed that 5 and 6 are connected by two hexa …

This Review discusses the recent developments in the field of synthetic chemistry of PAH–
porphyrin hybrids, emphasizing phenanthrene‐embedded carbaporphyrinoids and related …

Recent years have witnessed a resurgence of study in hydrocarbon belts due to their
potential applications in carbon nanotechnology. By contrast, heteroatom-embedded zigzag …

Hydrocarbon belts have drawn great attention because of their unique structures and
tantalizing properties. Although a few belts and heteroatom‐doped analogs have been …

Small-molecule fluorophores in the second near-infrared window (NIR-II, 1,000–1,700 nm)
have received widespread attention owing to their great breakthrough in deep-tissue …

Herein, we report the synthesis of a novel carbaporphyrin incorporating perylene diimide
(PDI) and dipyrromethane units. The twisted plane of the PDI subunits imbues …

A non‐aromatic expanded carbaporphyrinoid, incorporating two built‐in 2, 7‐pyrenylene
moieties was synthesized. The intrinsically labile structure was demonstrated by proton …

Aromatic and antiaromatic ring currents can reveal global electronic delocalization around
the circumference of π-conjugated macrocycles, although these phenomena are poorly …

Strained carbon nanohoops exhibit attractive photophysical properties due to their unique π-
conjugated structure. However, incorporation of such nanohoops into the pincer ligand of …
