Journal ArticleDOI
Photochemical deprotection of nitro-substituted benzenesulfenates via photoinduced electron transfer
TL;DR: The photochemical deprotection of alkyl 2,4-dinitrobenzenesulfenate was successfully achieved by addition of triethylamine, while it was unsuccessful without triethyamine as discussed by the authors.
On the Mechanism of Photoinduced Electron Transfer in Bridged Donor/ Acceptor Systems
TL;DR: In this article, mechanistic aspects of electron transfer (ET) reactions of two covalently linked molecular systems have been studied, applying fs to ns time resolved absorption and fluorescence techniques.

Tomasz Uchacz,Paweł Szlachcic,A.A. Fedorchuk,Ewa Gondek,Andrzej Danel,Bożena Jarosz,A.M. El-Naggar,A.A. Albassam,I.V. Kityk,G. Lakshminarayana,P. Czaja,Paweł Karasiński +11 more
TL;DR: In this paper, the photophysical properties of donor-acceptor based benzoxazoles were investigated by means of steady-state and time-resolved fluorescence techniques, and laser stimulated second-order optical effects (preliminary second harmonic generation) were studied.

Triplet recombination of radical ion pairs: CIDNP effects and DFT calculations on 1,2-dicyanoethylene
Heinz D. Roth,Ronald S. Sauers +1 more
TL;DR: The radical anion surface has minima in which the carbon and nitrogen skeleton is essentially planar; the central C-C bond is lengthened (weakened), but the barrier to geometric isomerization is still sizeable (31.2 kcal mol(-1).

Solvent, isotope, and magnetic field effects in the geminate recombination of radical ion pairs
TL;DR: In this article, the magnetic field dependence of the geminate recombination triplet yield of radical ion pairs generated via photoinduced electron transfer in polar solvents is investigated for the systems pyrene/N, Ndimethylaniline (Py/DMA), pyrene 3,5,dimethoxy•N,Ndimethynylinox•N and pyrene DMDMA, and the perdeuterated system Py•d10/dMA•d11.

Bindungszustand und Fluoreszenzspektren von Hetero-Excimeren
Dieter Rehm,Albert Weller +1 more
TL;DR: The structureless fluorescence spectra of more than one hundred heteroexcimers (unsymmetrical molecular complexes which are stable in the excited state) were measured in hexane or other inert solvents.
