Journal ArticleDOI
Synthetic approaches toward molecular and polymeric carbon allotropes
François Diederich,Yves Rubin +1 more
TL;DR: In this paper, a review of all-carbon molecules and polymers that differ from the familiar networks of graphite and diamond as well as from the fullerenes is presented.

Strategien zum Aufbau molekularer und polymerer Kohlenstoffallotrope
TL;DR: In this paper, a ubersicht uber organisch-chemische Synthesestrategien fur ausschlieslich aus Kohlenstoff aufgebaute Molekule and Polymere, welche strukturell von den bekannten Graphit-and Diamant-Netzwerken and auch von den Fullerenen abweichen.

Global Aromaticity in Macrocyclic Polyradicaloids: Hückel's Rule or Baird's Rule?
TL;DR: A type of macrocyclic polyradicaloid in which multiple frontier π-electrons are antiferromagnetically coupled with each other in a cyclic mode is investigated, raising questions about their possible global aromaticity and which rule they will follow.

TL;DR: In this article, two stable cyclopenta-ring-fused oligo(m -phenylene) macrocycles, 8MC-M and 10 MC-M, were synthesized with moderate polyradical character.

Nucleus-independent chemical shifts and local aromaticities in large polycyclic aromatic hydrocarbons
TL;DR: In this article, the bond resonance energy (BRE) pattern in polycyclic π-systems was used to estimate the degree of local aromaticity in each π system and individual rings were found to sustain diatropic currents.
