Chemical Properties

SLIGHTLY YELLOW TO BEIGE CRYSTALLINE POWDER

Uses

4-Benzoylbiphenyl (4-Phenylbenzophenone; HRcure-PBZ ) is a reagent used to synthesize multicolored mechanochromic luminogen molecules. HRcure-PBZ is a low odor photoinitiator, which is a molecule that absorbs photons upon irradiation with light and forms reactive species out of the excited state, which initiates consecutive reactions.

Application

4-Benzoylbiphenyl (HRcure-PBZ) is a benzophenone analog with large aromatic ring systems. Sakamoto et al. investigated the properties of benzophenone ketyl radical analogs with large aromatic ring systems, such as naphthyl phenyl ketone, 4-benzoyl biphenyl, and bis(biphenyl-4-yl)methanone in the excited state by using nanosecond–picosecond two-color two-laser flash photolysis[1].
