Poled polymeric materials have been extensively studied because of their potenial application in integrated opto electronics. Polyimides based second order nonlinear optical materials have attracted intensive attention because polyimides have high thermal stability, electrical and mechanical properties, and have been widely used in microelectronics. In this atricle, based on a brief introduction to the poled polymer, recent progress on polyimide based second order nonlinear optical materials was reviewed, including the design, synthesis and properties of the polyimides and their chromophores; poling methods and relaxation mechanism.
