Abstract: The cubic nonlinear-optical susceptibility of solutions and films of new metalloorganic polymers is studied by the z-scan method using 1064-nm, 40-ps laser pulses. The contribution of the electronic susceptibility is measured with the help of probe beams with circular and linear polarisations. The greatest electronic susceptibility amounting to – 9.5 × 10^-11 and – 1.7 × 10^-10 CGSE units is found in films of poly[(arylene)(ethynylene)silylene] and chromium-doped bis(aren)polyacrylonitrile, respectively.
