    摘要: The present invention relates to porphyrin and metal ion-containing monomers and polymers. The monomers ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently selected from H, alkyl having 1 to 6 carbon atoms, phenyl or phenyl substituted with 1 to 3 alkyl groups each having 1 to 6 carbons or with 1 to 3 halogen atoms and A is a metal atom, are used with a diamine or a dialdehyde respectively to produce a porphyrin polymer or a metal ion containing porphyrin polymer. These polymers are useful as electrical conductors and as liquid crystal polymers.

    摘要: Novel compositions and methods are provided for use in the stepwise, layer by layer fabrication of three-dimensional objects, in which a build material contains a metal having a covalent bond to a non-metal, and the layers are processed to produce the three-dimensional object at least in part through a chemical reaction which alters the covalent bond of the metal. In a first aspect of the invention the build material includes a metal that is covalently bound to a polymeric precursor. In another aspect of the invention, the build material includes a metal, Me, that is covalently bound to a first ligand, L.sub.1. Following deposition of the build material, the first ligand undergoes a redox reaction with a second ligand, L.sub.2, thereby breaking the covalent bond of the metal. In more preferred embodiments of this class, L.sub.1 and L.sub.2 react to form a gas, and the metal reacts to form an oxide such as MeSO.sub.x, MeNO.sub.x, MeCO.sub.x and so forth. In yet another aspect of the invention, multiple build materials are employed to provide non-uniformities such as electrical, thermal, and magnetic conduction paths, structural supports, chemical and wear resistant areas, and so forth.
