Soluble polyimides with acyridine orange groups (PI 1-5) was first synthesized from 3,6-bis(dimethylamino)acridine and five variousdianhydride. The titania domain size in the hybrid materials analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD)was around 40–100 nm. The prepared optically transparent films had tunable refractive index (1.583
