Two-photon spectroscopy of the biphenyl chromophore. The electronic excited states of biphenyl and fluorene below 50000 cm-1 [PDF]

open access: yes, 1985
The two-photon excitation spectra of biphenyl and fluorene in dil. soln. were measured up to 50,000 cm-1. Both spectra exhibit a medium intense band system in the range 32,000-42,000 cm-1, and a strong band above 45,000 cm-1. The lowest frequency feature

Influencing the conductance in biphenyl-like molecular junctions with THz radiation [PDF]

open access: yes, 2013
We investigate the torsional vibrations in biphenyl-like molecular junctions and transport properties in the presence of an external THz field. Ab-initio calculations including external electric fields show that the torsional angle {\phi} of a thiolated ...

Hierarchically structured biphenylene-bridged periodic mesoporous organosilica [PDF]

open access: yes, 2011
Novel composites of highly ordered and stable biphenyl-bridged periodic mesoporous organosilica (PMO) materials confined within the pores of anodic alumina membranes (AAM) were successfully synthesized by evaporation-induced self-assembly (EISA).

Crystal structure of (2′,3,6′-trichlorobiphenyl-2-yl)boronic acid tetrahydrofuran monosolvate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C12H8BCl3O2·C4H8O, crystallizes as a tetrahydrofuran monosolvate. The boronic acid group adopts a syn–anti conformation and is significantly twisted along the carbon–boron bond by 69.2 (1)°, due to considerable steric hindrance from ...
