摘要:
A nanostructured molecular unit and method for forming is described where a cationic porphyrin having an ethanolic substituent species and a metal in the porphyrin cavity is combined with an anionic porphyrin having a sulfonate substituent species and a metal in the porphyrin cavity to form by self-assembly a nanostructured molecular unit with a morphology comprising four dendritic elements connected at a central node.
摘要:
Metal nanostructures formed by photocatalytic interfacial synthesis using a porphyrin-stabilized emulsion template and the method for making the nanostructures. Catalyst-seeded emulsion droplets are employed as templates for hollow-nanoshell growth. The hollow metal nanospheres may be formed with or without inclusions of other materials.

摘要:
A porphyrin coordination polymer nanostructure comprising a network of pyridyl porphyrin molecules and coordinating metal ions coordinatively bound through the pyridyl groups. In some embodiments, the porphyrins are metalloporphyrins. A variety of nanostructures are formed by the network polymer, including nanospheres, polygonal nanostructures, nanorods, and nanofibers, depending on a variety of factors including coordination metal ion, porphyrin type, metal of the metalloporphyrin, and degree of agitation during nanostructure formation. Reduction of coordinating metal ions may be used to form metal nanoparticles on the coordination polymer nanostructure.
