Photochemical Reaction

On bright summer days, the sunlight all around us is breaking bad by breaking bonds. Chemical bonds. Ultraviolet light shatters the links between atoms in the DNA of our skin cells, potentially causing cancer. UV light also breaks oxygen bonds, eventually creating ozone, and cleaves hydrogen off oth more

Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently only one of the two forms is effectual in biology and medicine. Hitherto, completely converting this mixture into the desired enantiomer was deemed impossible. Dep more

A team of physicists from the University of Nebraska-Lincoln, Stanford University and Europe has captured the clearest glimpse yet of a photochemical reaction - the type of light-fueled molecular transformations responsible for photosynthesis, vision and the ozone layer. The researchers precisely re more

Like most coatings, paints, and maintenance products, water repellents are expected to comply with increasingly stringent regulations of Volatile Organic Compounds (VOC), which are any volatile carbon compounds that engage in atmospheric photochemica 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
