Second harmonic generation in self-assembled alternating multilayers of hemicyanine containing polymers and polyvinylamine

Assembly of noncentrosymmetric multilayers is a facile technique for preparing noncentrosymmetric films avoiding electrical poling procedures and problems from subsequent relaxation of the induced orientational order. A maximum X zzz of 13 × 10 −9 esu was achieved for the assembly of up to six layer...

Description
Summary:Assembly of noncentrosymmetric multilayers is a facile technique for preparing noncentrosymmetric films avoiding electrical poling procedures and problems from subsequent relaxation of the induced orientational order. A maximum X zzz of 13 × 10 −9 esu was achieved for the assembly of up to six layers. Current problems are the long-term hydrolysation of the hemicyanine nonlinear optical chromophores and the reduction of polar orientation with increasing layer thickness.
