Spin trapping studies of photochemical reactions

Spin trapping is a very useful technique to study the photochemistry of chemical photosensitizers that undergo electron or hydrogen-transfer (Type I) reactions upon UV or visible irradiation. The Type I photochemistry of chlorpromazine [2-chloro-N-(3-dimethylaminopropy1)-phenothiazine], 3,3'4'5-tetrachlorosalicylanilide and 3,4',5tribromosalicylanilide has been investigated using 2-methyl-2-nit...

Suppressing photochemical reactions with quantized light fields

Photoisomerization, that is, a photochemical reaction leading to a change of molecular structure after absorption of a photon, can have detrimental effects such as leading to DNA damage under solar irradiation, or as a limiting factor for the efficiency of solar cells. Here, we show that strong coupling of organic molecules to a confined light mode can be used to strongly suppress photoisomeriz...

Photochemical Reactions in Polymeric

Photochemical reactions have been examined in relation with the physical properties of the solid polymeric matrix in which they are carried out. Three main reaction types are considered: (i) photocrosslinking reactions resulting from cyclodimerization of unsaturated groups and from the decomposition of photolabile groups into very reactive species, e.g. nitrenes from azides; (ii) photoisomeriza...
