Effect of π–π Stacking Interfacial Interaction on the Properties of Graphene/Poly(styrene-b-isoprene-b-styrene) Composites

Nanomaterials, 2021
Interfacial interaction is one of the most important factors in the construction of high-performance graphene-based elastomer composites. In this paper, graphene/poly (styrene-b-isoprene-b-styrene) (SIS) composites were prepared with solution mixing ...

π-Depletion as criterion to predict π-stacking ability [PDF]

The screening of molecular targets benefits greatly from rational design criteria, which can detect the most promising candidates. We demonstrate that π-depleted polyaromatic molecules present superior π-stacking ability.

Synergistic 3D π–π networks enforce persistent foldamer configuration with tunable full-color circularly polarized luminescence

Communications Chemistry
Achieving molecular chirality with enantiostability in purely π-conjugated foldamers remains a substantial challenge due to inherently weak π-π stacking interactions and facile racemization.

1-Benzyl-3-methylquinoxalin-2(1H)-one

IUCrData, 2018
The asymmetric unit of the title compound, C16H14N2O, contains three independent molecules differing primarily in the orientations of the benzyl groups. Each independent molecule forms inversion related dimers via offset π-stacking interactions.
