Abstract
Poly(p-phenylenevinylene) (PPV) was used to show how colloidal assembly can be used to prepare 3D photonic crystals made from an organic semiconductor. PPV was chosen due to its electrical conductivity, strong luminescence, high optical gain, and large refractive index - a parameter that determines how strongly photonic mode density is modified in the photonic crystal. These characteristics make PPV an appropriate material to investigate how the periodic structure of the crystal enhances the optoelectronic properties of the polymer. Also, since PPV has significant light-induced refractive index change, it is also suitable for studying the complementary effect - how the polymer enhances the properties of the photonic crystal.
