Abstract

In this paper we report a new type of two-legged amphiphilic molecule spacers 1,10 bistearyl-4,6,13,15-Ictraene-18-nitrogencrown-6(NC), the principle being that the single leg of the optical nonlinear hemicyanine derivative (HD) (DAEP) dye might insert in the spacer molecules thus fastening the interleaved Langmuir Blodgett (LB) multilayers, and improve the degree of order and structural stability. Quadratic second harmonic intensity enhancement has been achieved up to 114 layer (57 bilayers) in the above mentioned LB multilayers
