LANGMUIR BLODGETT FILMS

摘要

Novel 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 structure are described (i) in which A and B have similar backbones with complementary chromophore groups (ii) in which A and B have similar backbones with complementary functional groups and (iii) in which A and B have related functional groups but complementary backbones. Preferred LB films contain the compound (I).
