Journal ArticleDOI
THE REACTIVITY OF CITRONELLOL and α-THUJENE WITH SINGLET OXYGEN. RATE CONSTANTS OF CHEMICAL REACTION and PHYSICAL QUENCHING*
TL;DR: In this article, the quantum yields of Rose Bengal sensitized photooxidation of citronellol and α-thujene have been determined as a function of added acceptor and compared with those of furfuryl alcohol as a standard.
Journal ArticleDOI
Micellar control of the photooxidation pathways of 10-methyl phenothiazine: electron versus energy transfer mechanisms.
TL;DR: The quantum yields of (1)O2 production by MPS solubilized in the dispersed pseudo-phase of aqueous micellar systems were found to be similar to those determined in solvents of various polarities, regardless of the anionic or cationic nature of the surfactant.
Journal ArticleDOI
Charge-Transfer-Komplexe mit Polymeren aus substituierten Spirocyclopropan-1.9′-fluoren-Verbindungen. 1. Mitt. Modellverbindungen und Oligomere
TL;DR: In this paper, the CT-Komplexes of Tetracyanathylen (TCNE) and tetracyanchinodimethan (TCNQ) with substituierten Spirocyclopropan-1.9′-fluorene derivatives as well as with a dimer and a oligoester of the same type have been determined.
Patent
Process and device for the degradation of organic compounds in aqueous solution by vuv photolysis of water and electrochemical production of dioxygen
TL;DR: In this article, an Independent claim is also included for the installation required for the process, which is required for UV photolysis in aqueous solution by far the most commonly used method.
Journal ArticleDOI
An N,N′-dialkyl-4,4′-bipyridinium-modified titanium-dioxide photocatalyst for water remediation – observation and application of supramolecular effects in photocatalytic degradation of π-donor organic compounds
Stefan H. Bossmann,Sabine Göb,Till Siegenthaler,André M. Braun,Koodali T. Ranjit,Itamar Willner +5 more
TL;DR: The presence of 2,4-dimethylphenol indicates that the main pathway of substrate oxidation proceeds via electron transfer from the adsorbed organic substrate to the "holes" within the valence band of the photoexcited semiconductors V2+-TiO2 and TiO2.
