Date Jan. 15, 1987.Langmuir-Blodgett(LB) films of ABAB structure in which the compounds A and B are different and contain complementary groups which result in non-centrosymmetry of the layer plane. Three types of structures are described: (1) in which A and B have similar backbones with complementary chromophore groups, (2) in which A and B have similar backbones with complementary functional groups, and (3) in which A and B have related functional groups but complementary backbones.
