The Uses of 4-Benzoylbiphenyl

4-Benzoylbiphenyl is a reagent used in the synthesis of multicolored mechanochromic luminogen molecules.

What are the applications of 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].
