Kanazawa University research: Solvent effects of siloxanes on donor-acceptor interactions KANAZAWA, Japan, May 11, 2021 /PRNewswire/ Researchers at Kanazawa University report in Chemical Communications how solvents influence the strength of donor-acceptor interactions. They found that silicone solvents, providing low compatibility, intensify donor-acceptor interactions between aromatic molecules compared to hydrocarbon solvents. Aromatic donor-acceptor (D-A) interactions are a type of non-covalent bond between a donor (electron-rich) and an acceptor (electron-deficient) aromatic molecules. Aromatic molecules feature one or more rings with delocalized electrons. The aromatic D-A interactions are widely used for building supramolecular structures, which are assembly of molecules formed by non-covalent bonds like building blocks. The supramolecular structures have smart properties such as external stimuli-responsiveness and self-repairing. The stability and smart pr ....
Date Time Solvent effects of siloxanes on donor-acceptor interactions Aromatic donor–acceptor (D–A) interactions are a type of non-covalent bond between a donor (electron-rich) and an acceptor (electron-deficient) aromatic molecules. Aromatic molecules feature one or more rings with ‘delocalized’ electrons. The aromatic D–A interactions are widely used for building supramolecular structures, which are assembly of molecules formed by non-covalent bonds like building blocks. The supramolecular structures have smart properties such as external stimuli-responsiveness and self-repairing. The stability and smart properties of supramolecular architectures formed by D-A interactions depend on characteristics of the D–A interactions in various circumstances. Shogo Amemori and colleagues from Kanazawa University have now investigated the solvent effects on a strength of D–A interactions. Their findings provide important insights into the origin of aromatic D–A inte ....
