A simple method for chemically synthesizing PANI inverse opals by templating colloidal crystals is presented. The use of dodecylbenzene sulfonic acid resulted in structures with reduced shrinkage, allowing the position of the optical stop band to be tuned. The conductivity of the inverse opals was increased, and that of PANI was estimated to be 8 S · cm −1 . The inverse opals were of good structural integrity and fidelity, and the overall thickness could be controlled by that of the templates. Optical reflection spectra provided additional evidence of the high crystalline quality of the samples. These inverse opals might be attractive materials for sensor applications and studies of novel optical properties.
