## Abstract Several kinds of azo‐dye polymer films of the guest‐host system were prepared by the spin‐coating method. Four disperse red (DR) dyes of DR1, DR19, DR54 and DR73 were chosen as second order nonlinear optical active chromophores with polymer matrixes such as poly (methyl methacrylate) PM
