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 —CHCH
2
or —CCH and Ar is an aromatic group. Methods and intermediates useful for making such compounds are also described.

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.
A (preferably nonaqueous) method of making a dipyrromethane is described. The comprises the steps of: (a) providing a reaction system consisting essentially of an aldehyde or acetal, excess pyrrole and a catalyst; (b) reacting the aldehyde or acetal with the pyrrole in the reaction system to form the dipyrromethane therein; (c) quenching the reaction system by adding a base thereto (preferably without simultaneously or concurrently adding water and/or an organic solvent thereto); (d) separating the catalyst from the reaction system; and then (e) separating the pyrrole from the reaction system to produce the dipyrromethane as a residual
