Abstract

Large scale of well-ordered macroporous π-conjugated polymer monoliths have been successfully prepared through a new approach using micrometer-sized naphthalene crystals as templates. The macroporous monoliths of poly(p-phenylenevinylene) (PPV) and poly(p-phenyleneethynylene) (PPE) grew along the unidirectional freezing direction inside the template naphthalene crystals which lead to the formation of controlling morphologies and homogeneous diameters. The polymer monoliths show straight and lamella macroporous structures. The diameters of pores and the thickness of pore walls can be controlled by tuning the freezing temperature.
