Abstract:

A new type of bifat-chain amphiphilic molecules 1,10-bistearyl-4,6,13,15-tetraene-18-nitrogencrown-6 (NC), was synthesized and adopted as an spacer for an optically nonlinear hemicyanine derivative(DAEP) dye to form interleaved Y-type LB multilayer films. The second harmonic (SH) intensity increased quadratically with the bilayer number due to improvement of the structural properties by insertion of the long hydrophibic chain of the DAEP between two fat-chains of NC.

Key words: second harmonic generation, Langmuir-Blodgett multilayer films, Crown, Hemicyanine
