A cycloparaphenylene can be thought of as the shortest possible cross section of an
armchair carbon nanotube. Although envisioned decades ago, these molecules—also …

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 …

Conspectus The discovery and creation of new forms of carbon have always transformed the
scientific landscape. For example, the discoveries of fullerenes, carbon nanotubes (CNTs) …

The generation of topologically complex nanocarbons can spur developments in science
and technology. However, conventional synthetic routes to interlocked molecules require …

The first synthesis of a cyclic oligophenylene possessing a radial π system was reported in
2008. In the short period that has elapsed since, there has been an ever-increasing level of …

[n] Cycloparaphenylenes (or “carbon nanohoops”) are cyclic fragments of carbon nanotubes
that consist of n para linked benzene rings. These strained, all sp2 hybridized macrocycles …

In the last 13 years several synthetic strategies were developed that provide access to [n]
cycloparaphenylenes ([n] CPPs) and related conjugated nanohoops. A number of potential …

The selective and predictable synthesis of structurally uniform carbon nanotubes (CNTs)
represents a long‐standing goal in both nanocarbon science and synthetic organic …

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

The design and synthesis of novel π‐conjugated macrocycles have been an attractive topic
in synthetic chemistry and material and supramolecular chemistry. The distortion caused by …
