Self-organizing assemblage of porphyrin molecules useful for converting light into chemical or electrical energy comprises porphyrin molecules with organophilic and hydrogen-bonding substituents

摘要

Self-organizing assemblage of porphyrin molecules comprises porphyrin molecules with at least four substituents, including at least one that increases solubility in organic solvents and at least one that forms hydrogen bonds with the substituents of adjacent molecules, where at least one of the H-bonding substituents comprises a recognition group that is attached to the porphyrin molecule though a spacer and is capable of forming multiple H bonds. An Independent claim is also included for the production of self-organizing assemblages by condensing dodecanal and/or an alkyl formylbenzoate with pyrrole and oxidizing the product to form a mixture of porphyrins with undecyl, 3,5-di-t-butylphenyl and/or alkoxycarbonylphenyl substituents; separating the porphyrins; hydrolyzing the alkoxycarbonyl groups to free acid groups; and esterifying these with alcohols bearing recognition groups.
