Dimerization of conjugated radical cations: An emerging non-covalent interaction for self-assembly
TLDR
This Focus Review highlights the recent advance in its application as an emerging non-covalent force for the construction of various supramolecular structures.Abstract:
Aromatic stacking has played a significant role in the design of discrete supramolecular systems. However, for many years, the stacking of conjugated radical cations has been considered only as a novelty due to its weakness. In recent years, it has been demonstrated that the stacking of conjugated radical cations, particularly those formed by bipyridinium or tetrathiafulvalene, can be enhanced remarkably when they are incorporated into rationally designed, preorganized frameworks or entrapped into a confined space. This Focus Review highlights the recent advance in its application as an emerging non-covalent force for the construction of various supramolecular structures.read more

Rethinking the term “pi-stacking”
TL;DR: In this paper, the authors review experimental and theoretical literature across several fields and conclude that the terms "pi stacking" and "pi-pi interactions" do not accurately describe the forces that drive association between aromatic molecules of the types most commonly studied in chemistry or biology laboratories.

TL;DR: Two switchable, palindromically constituted bistable [3]rotaxanes have been designed and synthesized with a pair of mechanically mobile rings encircling a single dumbbell, supporting the hypothesis that the cumulative nanoscale movements within surface-bound molecular muscles can be harnessed to perform larger-scale mechanical work.
