Abstract
We have prepared a second harmonic (SH) active polymer LB film of {N-e thyl-N-[4-(4-nitrophenylazo)phenyl]amino}ethyl acrylate/methyl methacr ylate) by means of horizontal deposition. Considerably high susceptibi lities chi(zzz) = 41.9 pm/V (1.00 X 10(-7) esu) and chi(zxx) = 7.33 pm /V (1.75 X 10(-8) esu) were obtained without poling process. Although the initial 4 monolayers show no SH activity, the monolayers more than fifth have a SH active structure.
