Nonlinear Optical Properties Of Platinum Poly-ynes

Transition metal-organic polymers have attracted considerable attention because of their potential applications to optoelectronic devices. Recently, we showed that platinum poly-ynes have large optical nonlinearities and low absorption in the visible and near infrared. Here, we report measurements showing the separation of nuclear and electronic contributions to the third-order optical nonlinearities (χ

). We also describe measurements of strong two photon absorption in the platinum poly-ynes.
