Arynes are among the most active organic intermediates and have found numerous
applications in expeditious preparation of substituted arenes. In the past 20 years, chemists …

Conspectus In recent years, synthetic transformations based on aryne chemistry have
become particularly popular, mostly due to the spread of methods to generate these highly …

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 …

The formation of two types of nanographenes from custom designed and synthesized
molecular precursors has been achieved through thermally induced intramolecular …

Helicenes are attractive non-planar polycyclic aromatic hydrocarbons with unique optical
and electronic properties. In recent years, the chemistry of “multiple helicenes” with plural …

The rational synthesis of nanographenes and carbon nanoribbons directly on nonmetallic
surfaces has been an elusive goal for a long time. We report that activation of the carbon (C) …

This paper presents the synthesis and comprehensive analysis of a highly contorted and
doubly negatively curved multihelicene compound, composed of three carbo [7] helicene …

We report a molecular design and concept using π‐system elongation and steric effects from
helicenes surrounding a triphenylene core toward stable chiral polycyclic aromatic …

Carbon, as an indispensable chemical element on Earth, has diverse covalent bonding
ability, which enables construction of extensive pivotal carbon-based structures in multiple …

Surface-assisted synthesis has become a powerful approach for generation of molecular
nanostructures, which could not be obtained via traditional solution chemistry. Nowadays …
