A comprehensive theoretical investigation of intramolecular proton transfer in the excited states for some newly-designed diphenylethylene derivatives bearing 2-(2-hydroxy-phenyl)-benzotriazole part.

Hongru Li et al.

Journal of fluorescence, 21(4), 1721-1728 (2011-03-04)

This article presents a comprehensive theoretical investigation of excited state intramolecular proton transfer (ESIPT) for some newly-designed diphenylethylene derivatives containing 2-(2-hydroxy-phenyl)-benzotriazole moiety with various substituted groups. The calculation shows the structural parameters and Mulliken charges of phototautomers enol (E) and

Development and validation of a fast gas chromatography mass spectrometry method for the quantification of selected non-intentionally added substances and polystyrene/polyurethane oligomers in liquid food simulants.

Emmanouil D Tsochatzis et al.

Analytica chimica acta, 1130, 49-59 (2020-09-08)

A simple, fast, sensitive and reliable method was developed for the simultaneous determination of 13 food contact materials (FCM) regulated substances and non-intentionally added substances (NIAS) migrating into official food simulants. The method has been optimized to quantify the monomers

Determination of the specific surface area of snow using ozonation of 1,1-diphenylethylene.

Debajyoti Ray et al.

Environmental science & technology, 45(23), 10061-10067 (2011-11-11)

We measured the kinetics of ozonation reaction of 1,1-diphenylethylene (DPE) in artificial snow, produced by shock freezing of DPE aqueous solutions sprayed into liquid nitrogen. It was demonstrated that most of the reactant molecules are in direct (productive) contact with
