Effects of π-π Stacking on Shale Gas Adsorption and Transport in Nanopores. [PDF]

ACS Omega, 2023
The π–π interaction is a prevalent driving force in the formation of various organic porous media, including the shale matrix. The configuration of π–π stacking in the shale matrix significantly influences the properties of shale gas and plays a crucial ...

Ordered π-conjugated polymer backbone in amorphous blend for high efficiency nonfullerene organic photovoltaics

Communications Materials, 2023
In π-conjugated polymers, the amorphous region absent from π–π stacking order typically limits polymer functions compared to the crystalline region with high π–π stacking order.

PbI6 Octahedra Stabilization Strategy Based on π‐π Stacking Small Molecule Toward Highly Efficient and Stable Perovskite Solar Cells

Advanced Energy Materials, 2023
The unavoidable iodine loss in the perovskite layer is closely related to carrier non‐radiative and device degradation. During the post‐annealing process, the fragile PbI bond is easy to break, leading to the formation of iodine vacancies and inducing ...

Intermolecular π-π Stacking Interactions Made Visible. [PDF]

J Chem Educ, 2021
Mixing the liquids hexafluorobenzene (1) and 1,3,5-trimethylbenzene (mesitylene, 2) results in a crystalline solid with a melting point of 34 °C. The solid consists of alternating π−π stacked pillars of both aromatics.

Complementary, Cooperative Ditopic Halogen Bonding and Electron Donor-Acceptor π-π Complexation in the Formation of Cocrystals

Molecules, 2022
This study expands and combines concepts from two of our earlier studies. One study reported the complementary halogen bonding and π-π charge transfer complexation observed between isomeric electron rich 4-N,N-dimethylaminophenylethynylpyridines and the ...
