Self-Recognizing π-π Stacking Interactions Designed for the Generation of Ultrastable Mesoporous Hydrogen-Bonded Organic Frameworks [PDF]

open access: yes, 2019
Creating crystalline porous materials with large pores is typically challenging due to undesired interpen-etration, staggered stacking, or weakened framework stability.

Energetics of π-π Stacking Interactions: Implications in the Phase Separation of Intrinsically Disordered Proteins [PDF]

open access: yes, 2021
π-π stacking interactions are found throughout the proteome and have been shown to play a role in the liquid-liquid phase separation of intrinsically disordered proteins; however, the structural and energetic properties of π-π interactions that drive ...

1-Methyl-3-(2-methylphenyl)-4-phenyl-1H-pyrazolo[3,4-d]pyrimidine

open access: yesIUCrData, 2017
In the title compound, C19H16N4, the pyrazolopyrimidine unit is slightly twisted. A combination of π-stacking and offset π-stacking interactions forms columns along the b-axis direction.

The use of a molecular balance derived from 5,5′-bipyrazole to calculate π-π stacking interactions [PDF]

open access: yes, 2013
Theoretical calculations have been carried out on 3,3′-dimethyl-1,1′-diphenyl-5,5′-bi-1H-pyrazole to evaluate its usefulness as a molecular balance to measure π-π stacking.

Influence of perylenediimide–pyrene supramolecular interactions on the stability of DNA-based hybrids: Importance of electrostatic complementarity

open access: yesBeilstein Journal of Organic Chemistry, 2014
Aromatic π–π stacking interactions are ubiquitous in nature, medicinal chemistry and materials sciences. They play a crucial role in the stacking of nucleobases, thus stabilising the DNA double helix.

The Role of π−π Stacking Interactions in Square Planar Palladium Complexes. Combined Quantum Mechanics/Molecular Mechanics QM/MM Studies [PDF]

open access: yes, 2016
Density functional (DFT) studies and hybrid QM/MM-DFT calculations demonstrate the importance of π−π stacking interactions in determining the structural features of two exemplary d8 palladium complexes, PdBr(p-NCC6H4)({S}-MeO-Biphep), 1, and PdBr(C6F5 ...

A Study of π – π Stacking Interactions in Rhenium Carbonyl Complexes Based on Backbone Functionalized Bis(pyrazolyl)methane Ligands [PDF]

open access: yes, 2022
π – π Stacking interactions are one of the most important non-covalent inter-molecular forces, which play an important role in the architecture of 1D and 2D networks of supramolecular chemistry.

Exploiting π–π Stacking for Stretchable Semiconducting Polymers [PDF]

open access: yes, 2018
Although intermolecular charge transport is known to occur via π–π stacking, the influence of π–π stacking on the mechanical properties of polymers has received little attention compared with other dynamic noncovalent interactions. Herein, we demonstrate

Crystal structure of (μ-N-allylthiourea-κ2S:S)bis[μ-bis(diphenylphosphanyl)methane-κ2P:P′]bis[bromidocopper(I)] acetonitrile disolvate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
The reaction of cuprous bromide with a mixture of 1,1-bis(diphenylphosphanyl)methane (dppm: C25H22P2) and N-allylthiourea (ATU: C4H8N2S) in acetonitrile yielded the title solvated dinuclear complex, [Cu2Br2(C4H8N2S)(C25H22P2)2]·2C2H3N or [Cu2Br2(ATU ...
