Metalloporphyrin polymer functionalized substrate

摘要

A method is provided for fabricating a metalloporphyrin polymer on a substrate. The method creates a functionalized substrate by attaching an anchor group of a linker, including a terminal alkyne group, to a substrate surface. The functionalized substrate is then exposed to metalloporphyrin monomers, where each metalloporphyrin monomer includes at least two terminal alkyne groups. A plurality of metalloporphyrin monomers (e.g., zinc porphyrin monomers) are thus linked via the metalloporphyrin monomer terminal alkyne groups, forming a metalloporphyrin polymer attached to the substrate. In one aspect, linking the plurality of metalloporphyrin monomers via the metalloporphyrin monomer terminal alkyne groups includes forming butadiyne groups between adjacent metalloporphyrins. Then, forming the metalloporphyrin polymer attached to the substrate includes attaching the metalloporphyrin polymer, via a metalloporphyrin monomer terminal alkyne group, to the terminal alkyne group of an associated linker. Alternatively stated, the metalloporphyrin polymer is attached to the substrate via a polyalkyne group.
