A dynamic intermolecular associates in structure of the smectic A phase induced by mixing of two nematogens 4-pentyloxy-4"-cyanobiphenyl (1, high polar), and hexyloxyphenylic ester of nonyl-benzoic acid (2, low polar) have been discovered with aid of C-13-NMR spectroscopy. They are connected by means of dipole-dipole interaction between CO-and CN-groups, and dispersion forces between complementary packed aryl fragments. An analysis of the C-13 chemical shifts and of the C-13 spin-lattice relaxation times, T-1, confirms the bilayer model of the molecular packing for induced SmA phase. By formation of such associates the carbonyl group of 2 continually exchanges a partner because of lateral diffusion. Moreover the aromatic ring of the COOAr group is situated normally to the layer plane between two biphenyl aromatic rings of compound 1. This fact facilitates the co-operative rotation of the aromatic rings of interacting molecules within bilayer.
