Abstract1,3-diphenylisobenzofuran (DPBF) is a fluorescent molecule which possesses a highly specific reactivity towards singlet oxygen (1O2) forming an endoperoxide which decomposes to give 1,2-dibenzoylbenzene. This reaction between DPBF and 1O2 can be followed by measuring the decrease in fluorescence intensity of DPBF. In order to check the specificity of DPBF toward free radicals a series of experiments was carried out in Triton-X micelles and in natural systems (rat liver microsomes), in…

PHOTOCHEMICAL FORMATION OF METASTABLE SPECIES FROM 1,3‐DIPHENYLISOBENZOFURAN *

Abstract— Photochemical formation of metastable species from 1,3‐diphenylisobenzofuran (DPBF) in solutions has been investigated. On irradiation at 410 nm, in the presence of oxygen, DPBF is

Low-level chemiluminescence of hydroperoxide-supplemented cytochrome c.

Singlet-oxygen dimol emission seems to be mainly responsible for the observed light-emission in ferricytochrome c; a mechanism that can account for the major part of the present experimental observations is proposed.

Singlet oxygen production from the reaction of superoxide ion with halocarbons in acetonitrile

There is controversy about the mechanism of singlet oxygen (/sup 1/O/sub 2/) formation from systems that contain superoxide ion (O/sub 2//sup .-/), halocarbons, and H/sub 2/O. Khan and Corey et al.

Production of Singlet Oxygen in Electrogenerated Radical Ion Electron Transfer Reactions

The electrochemical reduction of oxygen generated superoxide ion and the electrochemical oxidation of ferrocene yielded the ferricenium ion. Both of these ion radicals were produced alternately in
