Helicenes have attracted considerable attention due to their inherent helical chirality and
extended π-conjugation. Recently, rapid progress has been witnessed in the preparation of …

With the serendipitous discovery of crown ethers by Pedersen more than half a century ago
and the subsequent introduction of host–guest chemistry and supramolecular chemistry by …

Technologies for the creation of topological carbon nanostructures have greatly advanced
synthetic organic chemistry and materials science. Although simple molecular nanocarbons …

Highly emissive π-conjugated macrocycles with tunable circularly polarized luminescence
(CPL) have sparked theoretical and synthetic interests in recent years. Herein, we report a …

In this paper, we theoretically explore the physical mechanism of the fluorescent origin and
chiral nature of Möbius carbon nanobelts. The electron–hole recombination is promoted by …

For numerous enabling features and strategic virtues, contemporary alkyne metathesis is
increasingly recognized as a formidable synthetic tool. Central to this development was the …

We report herein the regioselective synthesis of all-carbon lemniscular nanohoops bis-po-
CC and bis-pm-TC by the rational control of ring closures at the different positions of planar …

Chiral shape‐persistent molecular nanocarbons are promising chiroptical materials; their
synthesis, however, remains a big challenge. Herein, we report the facile synthesis and …

We present the first helicene carbon nanoohop that integrates a [6] helicene into [7]
cycloparaphenylene. The [6] helicene endows the helicene carbon nanohoop with …

Expanded helicenes are expected to show enhanced chiroptical properties as compared to
the classical helicenes but the synthesis is very challenging. Herein, we report the facile …
