Annotation It was investigated the physical processes in the molecules, which have properties required in case of using as molecular switches, transistors, or other electronic elements of future computers. Studies show that in the molecules of biphenyl substituents the angle between the planes of the phenyl rings depends on the magnitude of the applied external electric field. So, the ratio of squares of cosines of the angles between the phenyl groups in the field 0.01 a.u. and without field reaches 18. It significantly changes the ability of electrons to move along the long axis of the molecule. By varying the nature of the substituents, we can obtain the molecule characteristics that make these molecules promising for future using. This effect provides the use of biphenyl substitutes as transistors in electrical circuits constructed on separate molecules.
