Third order nonlinear properties of new composite materials obtained by embedding A new type π-conjugated poly [2,1,3-benzoselenadiazole-(2,5-didodecyloxy-1,4-phenylene)ethynylene](PPE)in porous silicon are measured in 532nm. The picoseconds measurements show a significant increase of nonlinear refractive index not only with respect to the standard optical materials. The reason can be explained as follows, the Π-electron conjugation bond would be expected to have a significant effect on the ground and excited state dipole moments and electronic transition energies of the molecule and, consequently, could affect the third-order nonlinear optical property of the molecule. The result shows that it is a promising candidate for further material development and possible photonic device applications.
