Synthesis and studies on luminescent biphenyl compounds
Synthetic Metals, 2000 A series of new soluble compounds based on a combination of biphenyl and stilbene structural elements having a low tendency to crystallize is described. Investigations on the effect of different substituents on the photoluminescence (PL) are presented. The new biphenyls are suitable as blue emissive layers in light emitting diodes (LEDs).

Photocatalytic degradation of hydroxylated biphenyl compounds
Applied Catalysis B: Environmental, 1996The photocatalytic degradation of three hydroxylated bicyclic aromatic compounds (2,2′-dihydroxybiphenyl, 4,4′-dihydroxybiphenyl and 4-hydroxybiphenyl) in contact with TiO2, in aqueous unbuffered solution was achieved. The main intermediate, in all cases, was 1,2,4-trihydroxybenzene.

Effective Inhibition of Hydroxyl Radicals by Hydroxylated Biphenyl Compounds
Free Radical Research Communications, 1993In aqueous media, approximate rate constants for the reactions between hydroxyl radicals (.OH) and biphenyl compounds such as dehydrodieugenol, magnolol, honokiol, dehydrodidihydroeugenol, dehydrodivanillyl alcohol, and dehydrodicreosol were estimated by competition reactions for .OH between these biphenyls and 5,5-dimethyl-1-pyrroline-N-oxide (DMPO ...

OPTICAL STABILITY IN BIPHENYL, PHENYLPYRIDYL, AND BIPYRIDYL COMPOUNDS
Canadian Journal of Research, 1950 Comparable ortho-substituted compounds of the biphenyl, 2-phenylpyridyl, and 2,2′-bipyridyl type have been synthesized and resolved, and the resistance to racemization determined. The results are as would have been predicted on geometrical considerations only, the compounds containing nitrogen atoms in the rings not behaving in any abnormal manner.

Isolation of bioactive biphenyl compounds from the twigs of Chaenomeles sinensis
Bioorganic and Medicinal Chemistry Letters, 2016Investigation of the MeOH extract of Chaenomeles sinensis twigs resulted in the isolation of seven biphenyl compounds (1-7) including a new compound, chaenomin (1). The chemical structures of the isolated compounds were elucidated by extensive NMR data ((1)H and (13)C NMR, (1)H-(1)H COSY, HSQC and HMBC), specific optical rotation, and chemical reaction.
