to a novel reactive mesogen compound having ester bonds and imine linkages and a spacer group of variable length at both ends between three benzene rings, whereas a liquid crystal phase is represented in a wide temperature range by forming a polymer network by photo-polymerization, since thermal ...
Its synthesis was achieved starting from stilbene by heating the syn-syn-anti and syn-anti-anti conformers formed upon cyclization of a hexaphenylbenzene derivative, followed by racemic resolution.doi:10.1002/anie.198502221Dipl.-Chem. Wolfram Kissener...

In order to investigate further the polycyclic aromatic hydrocarbons (PAH) produced by benzene droplet combustion, we have obtained and analyzed a highly-concentrated benzene droplet combustion sample, using high pressure liquid chromatography (HPLC) with diode-array ultraviolet-visible (UV) absorbance ...
The pyrrolic carbon atom gives a signal at 131.40 ppm and the carbon atoms from the four benzene rings are present in the 149.36–113.60 ppm interval. The aromatic carbon atoms linked to methoxy groups produce a resonance signal at 157.97 ppm. Figure 4. The 13C-NMR spectrum of OH-3Me...
(Figure 3a). In each L2 molecule, the dihedral angles between the two terminal imidazole rings and the central benzene ring were all 81.588°. The plane of the carboxyl group formed a dihedral angle of 2.048° with the plane of the naphthalene ring in each 1-hydroxy-2-naphthoic acid ...
IN this investigation we have succeeded for the first time in obtaining the Raman spectra of o-diphenyl benzene and m-diphenyl benzene. We have studied these compounds with the view of obtaining some evidence about the nature and symmetry of their benzene rings and also to record their Raman ...
