A method of making a compound of Formula I′
comprises reacting a compound of the formula DLCHO, with a compound of the formula
to produce the compound of Formula I′. Methods of using the compounds are also described, particularly as intermediates for the synthesis of porphyrin rods, which porphyrin rods are in turn useful for (among other things) the production of molecular memory devices.

position. The dipyrromethane synthesis was carried out using a 2:1 ratio of 2-(RS)pyrrole/benzaldehyde with a catalytic amount of InCl3 at room temperature in the absence of any solvent. The α-RS group was removed by hydrodesulfurization using Raney nickel or nickel complexes. This stoichiometric synthesisusing the α-RS-protected pyrrole is in contrast to the traditional synthesis that employs an aldehyde
