Catalytic dehydrogenation of ethane over mononuclear Cr(III) surface sites on silica. part I. C - H activation by σ-bond metathesis
Mononuclear Cr(III)-silica models have been studied by quantum chemical methods with respect to catalytic activity toward dehydrogenation of ethane. Both cluster and slab models have been developed and used to explore the ...
Gating the photochromism of an azobenzene by strong host–guest interactions in a divalent pseudorotaxane
The ability of an E-configured azobenzene guest to undergo photoisomerisation is controlled by the presence of a complementary host. Addition of base/acid allowed for a weakening/strengthening of the interactions in the ...
Switching Diarylethenes Reliably in Both Directions with Visible Light
A diarylethene photoswitch was covalently connected to two small triplet sensitizer moieties in a conjugated and nonconjugated fashion and the photochromic performance of the resulting compounds was investigated. In ...
Combined near-infrared excited SEHRS and SERS spectra of pH sensors using silver nanostructures
Surface-enhanced hyper-Raman scattering (SEHRS) and surface-enhanced Raman scattering (SERS) of para-mercaptobenzoic acid (pMBA) were studied with an excitation wavelength of 1064 nm, using different silver nanostructures ...
