We have investigated the effect of a series of 18 solvents and mixtures of solvents on the production of singlet molecular oxygen (O2(1Δg), denoted as 1O2) by 9H-fluoren-9-one (FLU). The normalized empirical parameter E derived from ET(30) has been

The effects of microheterogeneous media (micelles and microemulsions) on the lifetime and, to our knowledge for the first time, on the emission of singlet molecular oxygen (O2 (a1Ag), denoted as 1O2) were investigated. Micellar media and various type

Photochemistry of the singlet oxygen [O2(1Δg)] sensitizer perinaphthenone (phenalenone) in N,N′-dimethylacetamide and 1,4-dioxane

1H-Phenalen-1-one (perinaphthenone), an efficient singlet oxygen [O2(1Δg)] sensitizer with a quantum yield of singlet oxygen production (ΦΔ) close to unity, has been proposed as a universal standard for O2(1Δg) studies. However, data about the ph

Vacuum-UV (172 nm) Actinometry. The Quantum Yield of the Photolysis of Water

Autor: Gernot Heit, Annette Neuner, Pierre-Yves Saugy, André M. Braun

Publikováno v: The Journal of Physical Chemistry A. 102:5551-5561

With the development of new light sources (Xe-excimer light sources), the vacuum-UV (VUV) photochemistry on a preparative scale is becoming technically feasible. Among the first potential technical applications, VUV photolysis of aqueous systems must
