Amine-Directed Hydrogen-Bonded Two-Dimensional Supramolecular Structures.
Utilizing pure amine hydrogen bonding is a novel approach for constructing two-dimensional (2D) networks. Further, such systems are capable of undergoing structural modifications due to changes in pH. In this study, we designed a 2D network of triaminobenzene (TAB) molecules that by varying the pH from neutral to acidic, form either ordered or disordered structures on Au(111) surface as reveale...

متن کاملSupramolecular PhanePhos-analogous ligands through hydrogen-bonding for asymmetric hydrogenation.
PhanePhos-analogous phosphorous ligands have been generated via self-assembly through hydrogen-bonding, and studied in rhodium-catalyzed asymmetric hydrogenation (up to 99% ee).
متن کاملHighly fluorescent supramolecular gels with chirality transcription through hydrogen bonding.
A highly fluorescent organogel with transparency was formed through a hydrogen (H)-bonding interaction between a non-fluorescent and achiral 2-(3',5'-bis-trifluoromethyl-biphenyl-4-yl)-3-(4-pyridin-4-yl-phenyl)-acrylonitrile (CN-TFMBPPE) monomer and chiral sergeant l-tartaric acid (TA) (or d-TA), with gel formation being accompanied by a drastic fluorescence enhancement as well as chirality ind...
متن کاملMotion of Water Molecules and Hydrogen Bonds
The *H N M R spin-lattice relaxation time 7 \ , C1 NQR frequency VQ, and C1 NQR spin-lattice relaxation time 7 \ Q of [ Z n ( H 2 0 ) 6 ] [SnCl6] (zinc hexachlorostannate(IV) hexahydrate) have been measured at temperatures between 77 and 350 K. The NQR spin echo signal with Vq— 15.689 MHz at 77 K showed a positive temperature coefficient attributable to O H C l type H-bonds in the crystal. vQ a...
