A method of making a bacteriochlorin is carried out by condensing a pair of compounds of Formula II to produce the bacteriochlorin, wherein R is an acetal or aldehyde group. The condensing may be carried out in an organic solvent, preferably in the presence of an acid. The bacteriochlorins are useful for a variety of purposes such as active agents in photodynamic therapy, luminescent compounds in flow cytometry, solar cells, light harvesting arrays, and molecular memory devices.

De novo synthesis of bacteriochlorins

A method of making an oxochlorin comprises the steps of oxidizing a chlorin to produce a mixture of hydronchlorin and oxochlorin, and then oxidizing the hydroxychlorin in said mixture, preferably with DDQ, to produce a mixture consisting essentially of oxochlorin. The step of oxidizing a chlorin is carried out by exposing the chlorin to alumina, typically in the presence of an oxidizing agent such as air or alumina. The oxidizing steps may be carried out in an organic solvent such as toluene. The chlorin is preferably a C-methylated chlorin, and is preferably metalated.
