In this work, we examined the profile of metabolites produced from the doubly para-substituted biphenyl analogs 4,4'-dihydroxybiphenyl, 4-hydroxy-4'-chlorobiphenyl, 3-hydroxy-4,4'-dichlorobiphenyl, and 3,3'-dihydroxy-4,4'-chlorobiphenyl by biphenyl-induced Pandoraea pnomenusa B356 and by its biphenyl dioxygenase (BPDO). 4-Hydroxy-4'-chlorobiphenyl was hydroxylated principally through a 2,3-diox...

There is evidence that many plant secondary metabolites may act as signal molecules to trigger the bacterial ability to metabolize polychlorinated biphenyls (PCBs) during the rhizoremediation process. However, the bases for the PCB rhizoremediation process are still largely unknown. The rhizobacterium Rhodococcus erythropolis U23A is unable to use flavanone as a growth substrate. However, on th...

Rhodococcus sp. WB1 is a polychlorinated biphenyl degrader which was isolated from contaminated soil in Zhejiang, China. Here, we present the complete genome sequence. The analysis of this genome indicated that a biphenyl-degrading gene cluster and several xenobiotic metabolism pathways are harbored.

Optical properties of biphenyl difluoroboron β-diketonates were studied in poly(lactic acid) (PLA) blends. Increased conjugation lowered the emission energy, decreased the singlet-triplet energy gap and yielded blue thermally activated delayed fluorescence (TADF). The properties of these biphenyl dyes may inform organic light emitting diode (OLED) and bioimaging agent design.

In the title compound, C(22)H(16)O(4), the 7-phenyl ring is inclined at dihedral angles of 36.73 (9) and 69.37 (9)° with respect to the biphenyl benzene rings. The two benzene rings of the biphenyl unit form a dihedral angle of 55.99 (8)°. There are no significant hydrogen bonds observed in the crystal of this compound.

A new sterically hindered isoindoline-based 1,3-bis(51-methyl-41-phenyl-21-thiazolylimino)isoindoline (1) was synthesized by fusion method with satisfyingly good yield. The structure of the newly synthesized compound was identified by FT-IR, UV-Vis, 1H-NMR, 13C-NMR and X-ray analysis.

Background: The cold-adapted Idiomarina sp. 185 from Antarctic shoreline sediment and the mesophilic A19 brackish Lake Faro (Italy) were screened for their efficiency in biosurfactant production by a temperature-mediated approach, when grown rich culture medium mineral supplemented with biphenyl. Methods: oxidation of polychlorobiphenyls standard screening tests performed, i.e., E24 index detec...

Abstract Phenanthroline ligands bearing two biphenyl ( L1 ) or tetraarylbenzene L2 substituents have been synthetized and used to prepare bis‐phenanthroline copper(I) complexes. Steric constraints are limited in the case of biphenyl‐substituted ligand [Cu( 2 ](BF 4 has obtained by reaction with [Cu(CH 3 CN) ). In contrast, large enough totally prevent formation corresponding homoleptic complex....

Abstract. General theoretical approach, based on projection operator techniques and scattering theory, applied to the electron transport through flexible molecular bridge is reviewed and explained within a simple model describing a biphenyl molecule connected between two metal leads. Transmission probability through the bridge and its current-voltage characteristics are calculated in one electr...

Two new inclusion compounds of 9,9'-spirobifluorene (SBF) incorporating benzene [(I), C25H16.C6H6] and biphenyl [(II), C25H16.C12H10], and a new polymorph of SBF [(III), C25H16] are reported. All three exhibit C-H...pi(arene) hydrogen bonds between adjacent SBF molecules. Compound (II) also contains biphenyl C-H to SBF pi-arene interactions. Collectively, hydrogen bonding gives rise to a chain ...
