Abstract

A new type of bifat-chain amphiphilic molecules, 1,10-bisteary1-4,6,13,15-tetraene-18-nitrogencrown-6 (NC), was adopted as a spacer for an optically nonlinear hemicyanine derivative (HD) dye to form interleaving Y-type LB multilayers. The second harmonic (SH) intensity increased quadratically with the bilayer number up to 116 bilayers due to improvement of the structural properties by insertion of the long hydrophobic tail of the HD between two fat-chains of NC.
