Supramolecular polymer can be formed from amphiphilic block copolymer polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) and 4'-iodo-4-dimethylaminoazobenzene molecule through halogen bond. In this paper, honeycomb ordered porous films were prepared by static breath figure (BF) method by this supramolecular polymer. The effects of IAzo content and light illumination conditions on the morphology of supramolecular polymer porous film were studied in detail. The formation of the supramolecular polymer, the surface and the fracture morphology of the porous film were characterized by infrared spectroscopy and scanning electron microscopy. These results showed that with the increase of IAzo content, the pore size of supramolecular polymer porous film gradually increased. In addition, under the irradiation of linearly polarized light, the round hole structure of the porous film can be converted into rectangular holes or rhombic holes according to the change of polarization direction of linearly polarized light. The degree of deformation increases with the increase of azobenzene content and the extension of illumination time. The porous film prepared from this azobenzene-containing supramolecular polymer realizes the light regulation of porous structure by non-synthetic means.
