Abstract
Abstract The multipole model of molecular asymmetry of rod-like and disc-like mesogens was developed by us earlier (1981). It included the electrical, sterical and biphilic asymmetry. That model was generalized later on (1985) by including the flexibility asymmetry as well. Accordingly, mesogens were classified as generalized multipoles: monopoles, dipoles, quadrupoles etc. Furthermore, the generalized dipoles were considered as functions of the generalized fields by introducing generalized polarizabilities. These new lines of development of the model are reviewed here. They are especially important for lyotropics and membranes. Since 1981 a number of new mesogens corresponding to the theoretical predictions of the model were synthesized. We are applying our general classification to the following substances: cone-shaped discotics, flexible core discotics, discoidal amphiphilics, phasmids, biforked mesogens etc. Peculiarities in the structural organization of the tilted compounds are qualitatively discuss...
