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.

porphyrin or use of a dimethyl or diethyl phosphonate substituted precursor in a porphyrin-forming reaction. The latter approach makes use of dipyrromethane building blocks bearing mono or tripodal dialkyl phosphonategroups. The zinc porphyrin-tripodal compound bearing benzylphosphonic acid legs tethered to a SiO2 surface (grown on doped Si) was electrically well-behaved and exhibited characteristic porphyrin

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.

Donor-π-Acceptor (D-π-A) type carbazole-porphyrin dyads and triads were synthesized in good yields through palladium catalyzed coupling reactions. The length of the spacer between the D (carbazole) and A (porphyrin) was varied from “phenylethyne” to “ethyne linkage”. The effect of the linker length on the spectral properties of these D-π-A dyads and triads was studied. The N-butyl-3-ethynyl-carbazole was
