High Solid Fluorescence of a Pyrazoline Derivative through Hydrogen Bonding.
Pyrazoline and its derivatives often exhibit strong emissions in dilute solutions, but their emission intensity is often dramatically reduced in the solid state due to strong intermolecular interactions between neighboring molecules. In this report, we successfully synthesized a new pyrazoline 4-(3-(4-(decyloxy)phenyl)-1-(2,3,5,6-tetrafluoro-4-(trifluoromethyl)phenyl)-4,5-dihydro-1H-pyrazol-5-y...
متن کاملStructure and Hydrogen Bonding of Solid N
Crystalline N-alkyl-N-arylthioureas with ortho hydroxyl and para or meta methyl substituents to the phenyl ring were studied by single crystal X-ray diffraction, IR and solid state C CP MAS NMR. Two different modes of association were found: i) intermolecular NH...S bonds and NH not involved in hydrogen bonding in N-methyl-N(2-hydroxy,5-methylphenyl)thiourea 1, ii) cyclic dimers with two NH...S...
متن کاملSpin Transfer through Hydrogen Bonding
A polarised-neutron diffraction experiment on [Co(NH3)5(H20)][Cr(CN)6] shows the unexpected features of spin populat ions on the cobalt ((0.5(2) e) and the "ammine" hydrogen (0.8(1) e in total) atoms. A local density approximation DV-Xa calculation on a unit that models the molecular geometry in the crystal returns features that are broadly in agreement with the experiment. The calculation also...
متن کاملNH+-F hydrogen bonding in a fluorinated "proton sponge" derivative: integration of solution, solid-state, gas-phase, and computational studies.
We report detailed studies on the characterization of an intramolecular NH-F hydrogen bond formed within a fluorinated "proton sponge" derivative. An ammonium ion, generated from 8-fluoro-N,N-dimethylnaphthalen-1-amine, serves as a charged hydrogen bond donor to a covalently bound fluorine appropriately positioned on the naphthalene skeleton. Potentiometric titrations of various N,N-dimethylnap...
متن کاملHydrogen bonding in solid ammonia from ab initio calculations
We have carried out ab initio simulations on the ambient pressure phase I of solid ammonia, and on the high-pressure phase IV. Our plane-wave pseudopotential calculations yield very good agreement with existing structural data, lattice energies, and equations of state. We have also studied the tendency toward symmetrization of the hydrogen bonds at high pressures and find that, unlike pure ice,...
