Knotting matters: orderly molecular entanglements

Z Ashbridge, SDP Fielden, DA Leigh, L Pirvu… - Chemical Society …, 2022 - pubs.rsc.org
Entangling strands in a well-ordered manner can produce useful effects, from shoelaces and
fishing nets to brown paper packages tied up with strings. At the nanoscale, non-crystalline …

[HTML][HTML] Classic highlights in porphyrin and porphyrinoid total synthesis and biosynthesis

MO Senge, NN Sergeeva, KJ Hale - Chemical Society Reviews, 2021 - pubs.rsc.org
Porphyrins feature prominently in nature, be it as enzymatic cofactors, electron and exciton

From macrocycles to quantum rings: Does aromaticity have a size limit?

M Jirásek, HL Anderson, MD Peeks - Accounts of Chemical …, 2021 - ACS Publications
Conspectus The ring currents of aromatic and antiaromatic molecules are remarkable
emergent phenomena. A ring current is a quantum-mechanical feature of the whole system …

Template-directed synthesis of molecular nanorings and cages

PS Bols, HL Anderson - Accounts of chemical research, 2018 - ACS Publications

molecules. A template organizes the reactants and provides information to promote …

Global aromaticity at the nanoscale

M Rickhaus, M Jirasek, L Tejerina, H Gotfredsen… - Nature …, 2020 - nature.com
Aromaticity can be defined by the ability of a molecule to sustain a ring current when placed
in a magnetic field. Hückel's rule states that molecular rings with [4 n+ 2] π-electrons are …

Vernier template synthesis of molecular knots

Z Ashbridge, E Kreidt, L Pirvu, F Schaufelberger… - Science, 2022 - science.org
Molecular knots are often prepared using metal helicates to cross the strands. We found that
coordinatively mismatching oligodentate ligands and metal ions provides a more effective …
