摘要：

We demonstrate that the Langmuir-Blodgett (LB) method provides us with polymer films of considerably high chi(2). The investigation has been made on the monolayer films of PMMA partially substituted for disperse red at the air/water interface (L film) or on a substrate (LB film). The maximum surface susceptibility chi(s,zzz) of the L film is 2.1 x 10(-6) pm/V (5.1 X 10(-15) esu). Fairly high bulk susceptibility chi(zzz) = 9.8 pm/V (2.35 x 10(-8) esu) is obtained in a 3D-layered LB film of high optical quality. The orientational change of the chromophore during compression is also discussed.
