Macroporous poly(aromatic amine): Synthesis and film fabrication

New soluble polymers derived from oxidation of 1H,2H-dihyroperimidines and related to poly(1,8-diaminonaphthalene) were synthesized and found to form hexagonally structured macroporous films (macroporous poly(aromatic amine)) derived from the formation of breath figures. The polymers formed well-ordered macroporous films with homogeneous hole sizes between 0.2 and 1 μm. The polymers also formed other structures including nanofibers, microparticles and hollow membranous objects.
