this paper proposes a new material design idea that utilizes π-π interactions between graphene and compounds with conjugated structures in order to achieve uniform dispersion of graphene in the metal matrix and thus enhance the performance of composites. Based on this design idea, we used nicotinic...

The molecules of 2-benzoyl-1-benzofuran, C 15 H 10 O 2 , (I), interact through double C—HO hydrogen bonds, forming dimers that are further linked by C—HO, C—Hπ and π–π interactions, resulting in a three-dimensional supramolecular network. The dihedral angle between the benzoyl ...

The recent surge of interest in the control of molecular organization in both the solution state (i.e. self-assembly) and the solid state (i.e. crystal engineering) has led researchers to recognize increasingly the importance of weak noncovalent interactions. The design and synthesis of an effic...
Competition among weak intermolecular interactions can lead to polymorphism, the appearance of various crystalline forms of a substance with comparable cohesive energies. The crystal structures of 2-fluorophenylacetylene (2FPA) and 3-flu... AG Dikundwar,R Sathishkumar,TN Guru Row,... - 《Crystal...
In a data set of 20 proteins, we observed 2086 amide–π interactions, all of which were part of the protein backbone. Phe and Tyr residues were found to be involved in amide–π interactions more frequently than Trp or His. The most favorable amide–π interactions occurred within a pair...
