This invention is a monomer comprising at least two dienophile groups and at least two ring structures which ring structures are characterized by the presence of two conjugated carbon-to-carbon double bonds and the presence of a leaving group L, wherein L is characterized that when the ring structure reacts with a dienophile in the presence of heat or other energy sources, L is removed to form an aromatic ring structure. This invention is also curable oligomers and polymers and highly cross-linked polymers made with such monomers. Moreover, this invention is a method of making porous films by combining such monomers or their oligomers with a porogen, curing the polymer and removing the porogen.
