Substituent and Heteroatom Effects on π-π Interactions: Evidence That Parallel-Displaced π-Stacking is Not Driven by Quadrupolar Electrostatics.

Journal of the American Chemical Society
Stacking interactions are a recurring motif in supramolecular chemistry and biochemistry, where a persistent theme is a preference for parallel-displaced aromatic rings rather than face-to-face π-stacking.

Applications of π-π stacking interactions in the design of drug-delivery systems.

Journal of Controlled Release, 2019
Noncovalent forces are of considerable importance in the formation of self-assembled drug-delivery systems. In addition to non-destructively linking the delivery vehicle and guest drug, they provide multiple advantages, including protecting the structure

π–π Stacking Modulation via Polymer Adsorption for Elongated Exciton Diffusion in High‐Efficiency Thick‐Film Organic Solar Cells

Advances in Materials
Developing efficient organic solar cells (OSCs) with thick active layers is crucial for roll‐to‐roll printing. However, thicker layers often result in lower efficiency. This study tackles this challenge using a polymer adsorption strategy combined with a

Long-Range π-π Stacking Brings High Electron Delocalization for Enhanced Photocatalytic Activity in Hydrogen-Bonded Organic Framework.

Angewandte Chemie
Unlike many studies that regulate transport and separation behaviour of photogenerated charge carriers through controlling the chemical composite, our work demonstrates this goal can be achieved through simply tuning the molecular π-π packing from short ...
