The singlet oxygen generation of photosensitizers were monitored by photolysis of 1,3-diphenylisobenzofuran (DPBF). 1,2-Dibenzoylbenzene absorbs at <300 nm, therefore making DPBF an optimal chemical trap for detecting singlet oxygen, as most photosensitizers absorb <400-600 nm. This allows for an accurate determination of the photodegradation ...

Utilization of a fluorescence dye, 1,3-diphenylisobenzofuran (DPBF) as a detector of superoxide anion radical (O2*-) was examined. The fluorescence intensity of DPBF incorporated in phospholipid liposomes consisting of phosphatidylcholine (PC) and phosphatidylserine (PS) is effectively quenched by incubation with xanthine/xanthine

1,3-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.

1,3-Diphenylisobenzofuran (DPBF) has been developed as a selective probe for the detection and quantitative determination of hydrogen peroxide in samples containing different reactive nitrogen and oxygen species (RNOS).

2020年3月1日 · Reactivity of DPBF with singlet oxygen is diffusion-limited in ethanol/water. ABDA is much less sensitive than DPBF, but is specific to singlet oxygen. Quantitative results provide calibration for determining singlet oxygen yields.

1,3-Diphenylisobenzofuran (DPBF) has been developed as a selective probe for the detection and quantitative determination of hydrogen peroxide in samples containing different reactive nitrogen and oxygen species (RNOS).

2011年11月1日 · The photostability and fluorescence properties of 1,3-diphenylisobenzofuran (DPBF), a popular singlet oxygen (1 O 2 or 1 Δ g) trapping-agent used in various solvents, are examined by UV–vis absorption, steady-state and time-resolved fluorescence techniques, as well as laser flash photolysis.

2012年9月26日 · 1,3-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 (RO·), and alkylperoxy (ROO·) radicals. In all cases the reaction product is 1,2-dibenzoylbenzene.
