Patent ID: 8618281

Claim:
A method for the synthesis of a porphyrin rod, comprising the steps of: (a) providing a compound of the formula Aâ€²-L-B, wherein A is a 1,9-bis(thio)dipyrromethane, L is a linker group or covalent bond, and B is a dipyrromethane-1,9-dicarbinol; (b) providing a compound of the formula C-L-D; wherein C is a dipyrromethane, L is a linker group or covalent bond, and D is a 1,9-diacyldipyrromethane or surface attachment group; (c) condensing said compound of formula Aâ€²-L-B with said compound of formula C-L-D to produce an elongated compound of formula A-L-D, wherein A is a 1,9-bis(thio)dipyrrin, L is a linker group, and D said a 1,9-diacyldipyrromethane or surface attachment group, with said linker group comprising at least one porphyrinic macrocycle.
