Abstract: This invention provides redox-active molecules attached to polypodal (e.g., bipodal, tripodal, quadrapodal, pentapodal, etc.) tethers that can be used for attachment of the redox-active molecules to a substrate (e.g., an electrode). The tethered redox-active molecules are useful for the fabrication of memory devices.

Abstract: This invention provides a new procedure for attaching molecules to semiconductor surfaces, in particular silicon. The molecules, which include, but are not limited to porphyrins and ferrocenes, have been previously shown to be attractive candidates for molecular-based information storage. The new attachment procedure is simple, can be completed in short times, requires minimal amounts of material, is compatible with diverse molecular functional groups, and in some instances affords unprecedented attachment motifs. These features greatly enhance the integration of the molecular materials into the processing steps that are needed to create hybrid molecular/semiconductor information storage devices.

Abstract: A method of making a phosphono-substituted dipyrromethane comprises reacting an aldehyde or acetal having at least one phosphono group substituted thereon with pyrrole to produce a phosphono-substituted dipyrromethane; and wherein the phosphono is selected from the group consisting of dialkyl phosphono, diaryl phosphono, and dialkylaryl phosphono. Additional methods, intermediates and products are also described.

Abstract: Porphyrin compounds having a surface attachment group coupled thereto at the 5 position are described. The surface attachment group has the formula: wherein R is —CHCH2 or —CCH and Ar is an aromatic group. Methods and intermediates useful for making such compounds are also described.
