摘要：
The influence of 4-aminobenzonitrile (ABN) on the mesomorphic, optical, dielectric and orientational properties of 4-(trans-4'-pentylcyclohexyl) benzonitrile (5PCH) and 4-hexyloxy-4'- cyanobiphenyl (5OCB) was studied. It was shown that addition of (ABN) results in dielectric anisotropy increase. At the same time LC birefringence weakly depends on additive concentration. The increase in Kirkwood factor was shown which points out the decrease in dipole-dipole association due to H-bonding of LC-non-mesogen.
