Anion Recognition by Charge Neutral Electron-deficient Arene Receptors

Anion-? interactions are newly emerging non-covalent interactions and have attracted considerable attention from both theoreticians and supramolecular chemists. This short review article summarizes the recent advances in anion recognition using charge neutral electron-deficient aromatic compounds

3-(4-Fluoro­phen­yl)-1-(4-methoxy­phen­yl)prop-2-en-1-one

The title compound, C16H13FO2, was prepared from 4-methoxy­hypnone and 4-fluoro­benzophenone by Claisen–Schmidt condensation. All the bond lengths and bond angles are in normal ranges. The dihedral angle formed by the two benzene rings is 33.49 (2)°. The crystal packing is stabilized by inter­molecular C—H⋯O hydrogen-bonding inter­actions

Mercury, Cadmium and Lead Biogeochemistry in the Soil–Plant–Insect System in Huludao City

Mercury, cadmium, and lead concentrations of ashed plants and insects samples were investigated and compared with those of soil to reveal their biogeochemical processes along food chains in Huludao City, Liaoning Province, China. Concentration factors of each fragments of the soil–plant–the herbivorous insect–the carnivorous insect food chain were 0.18, 6.57, and 7.88 for mercury; 6.82, 2.01, and 0.48 for cadmium; 1.47, 2.24, and 0.57 for lead, respectively. On the whole, mercury was the most largely biomagnified, but cadmium and lead were not greatly accumulated in the carnivorous insects as expected when the food chain extended to the secondary consumers. Results indicated that concentration factors depended on metals and insects species of food chains

Hybrid exciton-polaritons in a bad microcavity containing the organic and inorganic quantum wells

We study the hybrid exciton-polaritons in a bad microcavity containing the organic and inorganic quantum wells. The corresponding polariton states are given. The analytical solution and the numerical result of the stationary spectrum for the cavity field are finishedComment: 3 pages, 1 figure. appear in Communications in Theoretical Physic

3-(5-Methyl-2-fur­yl)-1-(p-tol­yl)-2-propen-1-one

The title compound, C15H14O2, was prepared from 4-methyl­hypnone and 5-methyl­furfural by Clasion–Schmidt condensation. All of the bond lengths and bond angles are in normal ranges. The dihedral angle formed by the benzene ring and furan ring is 5.31 (2)
