1,3-Diphenylisobenzofuran Chemical Properties,Uses,Production

Uses

1,3-Diphenylisobenzofuran is a useful research chemical.

Chemical Properties

yellow to greenish needle-like crystalline solid

Uses

1,3-Diphenylisobenzofuran(DPBF) was used as a fluorescent probe for detection of superoxide anion radical (O₂) inside the membrane lipid layer by DPBF fluorescence quenching method. 1,3-Diphenylisobenzofuran(DPBF) was used as quencher during the photoinactivation of TA-3 mouse mammary carcinoma cells containing hematoporphyrin. 1,3-Diphenylisobenzofuran(DPBF) was used to study the single crystal molecular structure and solution photophysical properties of DPBF.

General Description

1,3-Diphenylisobenzofuran is a fluorescent dye.1,3-Diphenylisobenzofuran is the model compound in studies of singlet fission.

Properties and Applications

The photostability and fluorescence properties of 1,3-diphenylisobenzofuran (DPBF) has been studied. DPBF is found to be easily photolyzed even if it is only exposed to the weak daylight in halogen-containing solvents in the absence of singlet oxygen. DPBF in DMF, DMSO, etc., on the other hand, is stable enough to enable fluorescence measurements^[1].

Purification Methods

Recrystallise it from EtOH or EtOH/CHCl3 (1:1) under red light (as in photographic dark rooms) or from *benzene in the dark. [Beilstein 17/2 V 503.]
