4′-(Morpholinomethyl)biphenyl-2-carbonitrile
In the title compound, C(18)H(18)N(2)O, the morpholine ring adopts a chair conformation and the dihedral angle between the aromatic rings is 49.16 (7)°. In the crystal, weak C-H⋯π inter-actions may help to establish the packing.
متن کاملPVT Measurements on 4'-w-Hexyl-Biphenyl-4-Carbonitrile (6CB) and 4 -w-Heptyl-Biphenyl-4-Carbonitrile (7CB) up to 300 MPa
P, Vm, 7" data were established for 4'-n-hexyl-biphenyl-4-carbonitrile (6CB) and 4'-n-heptyl-biphenyl-4-carbonitrile (7CB) between 300 and 370 K up to 300 MPa, and specific volumes were determined for the liquid crystalline, isotropic, and also partly for the crystal phases. Volume and enthalpy changes at the phase transitions are also presented. In the case of 6CB, a new crystal phase has been...
متن کامل3′,4′-Dimethoxybiphenyl-4-carbonitrile
The title compound, C(15)H(13)NO(2), was prepared through a palladium-catalysed Suzuki-Miyaura coupling reaction. The dihedral angle between the biphenyl rings is 40.96 (6)°. The meth-oxy groups are twisted slightly out of the plane of the benzene ring [C-C-C-C torsion angles = -3.61 (18) and 12.6 (2)°]. The packing of the molecules is stabilized by van der Waals inter-actions.
متن کاملPVT Measurements on 4'-/i-Octyl-Biphenyl-4-Carbonitrile (8CB) up to 300 MPa
P, Vm, Tdata have been measured for the smectic, nematic and isotropic phases of 4'-n-octyl-biphenyl-4-carbonitrile (8CB) in the temperature range 300-370 K and pressures up to 300 MPa. At atmospheric pressure all phase transitions appear to be of first order due to a discontinuity in the density. The volume change at the smectic A nematic transition is only a tenth of the volume change at the ...
متن کامل4'-Octyloxybiphenyl-4-carbonitrile polymorph III.
The title compound, C21H25NO, is a member of a well known family of liquid crystals (4-oxy-4'-cyanobiphenyls, OCBs) and packs in lamellar-type bilayers in the solid state, through CN...H hydrogen bonds. This packing type is analogous to that found of other members of the n-OCB homologous series, viz. 7-OCB and 9-OCB.
