Nonlinear optical properties of Langmuir-Blodgett films from two crowned azobenzenes

Article abstract of DOI:10.1246/cl.1998.1205

Two crowned azobenzene derivatives APCM and APCN were synthesized and incorporated into a β-cyclodextrin derivative ACD. Both APCM/ACD and APCN/ACD formed a stable Langmuir monolayer at the air-water interface. Multilayer Langmuir-Blodgett (LB) films with an ordered lamellar structure were constructed from APCM/ACD and APCN/ACD monolayers which showed a nonlinear polarisability (β) of 4 × 10^-29 and 1 × 10^-30 esu, respectively, after a month of storage.
