Photochemical Reaction

Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid dropl more

Starting from available chemicals, a German team of researchers successfully completed the total synthesis of agarozizanol B, an interesting natural substance found in agarwood. As described in the journal Angewandte Chemie, the key sequence in the relatively short synthetic pathway is a photochemic more

The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these contribute to the formation of aerosol particles as a precursor of raindrops and therefore impact the growth of clouds and pH of rainwater. In previous atmospheric ch more

CF3-containing spiro-epoxyoxindoles were successfully prepared via the Corey–Chaykovsky reaction of N-alkyl isatins with the ylide generated from Ph2S+CH2CF3OTf− with almost exclusive diastereoselectivity. Further derivatizations of these spiro-epoxyoxindoles were explored via a photochemical reacti more

The primary photochemical reaction of the green-absorbing proteorhodopsin is studied by means of a hybrid quantum mechanics/molecular mechanics (QM/MM) approach. The simulations are based on a homology model derived from the blue-absorbing proteorhodopsin crystal structure. The geometry of retinal a more

Polymeric carbon-nitride materials consisting of triazine or heptazine units have recently attracted vast interest as photocatalysts for water splitting with visible light. Adopting the hydrogen-bonded triazine-water complex as a model system, we explored the photochemical reaction mechanisms involv more
