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… 

Kinetics of the reaction between 1,3-diphenylisobenzofuran and nitrogen dioxide studied by steady-state fluorescence

Abstract1,3-Diphenylisobenzofuran (DPBF) is a fluorescent molecule which is believed to react highly specifically toward reactive oxygen species such as singlet oxygen (1O2), hydroxy (HO·), alkyloxy

The development of 1,3-diphenylisobenzofuran as a highly selective probe for the detection and quantitative determination of hydrogen peroxide

1,3-Diphenylisobenzofuran responds to hydrogen peroxide in a very specific way with the limits of detection and quantitation of 88 and 122.8 μM, respectively.

An analysis of the photophysical and optical limiting properties of a novel 1,3,5-tristyrylBODIPY dye

The synthesis and characterization of a novel dibrominated 1,3,5-tristyrylBODIPY dye is reported, and its potential utility as a singlet oxygen photosensitizer and optical limiting material is

Synthesis and photochemical properties of pH responsive tris-cyclometalated iridium(III) complexes that contain a pyridine ring on the 2-phenylpyridine ligand.

The preparation of some new pH-responsive Ir(III) complexes that contain three pyridyl groups at the 5'-position of the 2-phenylpyridine (ppy) ligand are reported on and the pH-dependent emission change of these complexes is discussed.

Novel Silicon Phthalocyanines Bearing Triethylene Glycol Groups: Photophysical and Photochemical Properties as well as pH-Induced Spectral Behaviour

Novel silicon (IV) phthalocyanines peripherally substituted by triethylene glycol groups and bearing axial hydroxyl groups were synthesized and fully characterized by using different analyses techniques, making them good candidates as photosensitizer for PDT.

Light-Activated Zirconium(IV) Phthalocyanine Derivatives Linked to Graphite Oxide Flakes and Discussion on Their Antibacterial Activity

In search of an effective antibacterial agent that is useful in photodynamic therapy, new derivatives of zirconium(IV) phthalocyanine (ZrPc) complexes were obtained and linked to graphite oxide




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
