Schizophyllan Acts as a One-dimensional Host to Accommodate 5,10,15,20-Tetrakis(4-carboxyphenyl)porphyrinatozinc Acetate to Produce Its Fibrous Superstructure

Abstract

Abstract We established a novel strategy to construct porphyrin-nanofibers which may mimic a fibrous porphyrin-assembly observed in a natural light harvesting system in green bacterium. Our strategy utilizes alignment of 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrinatozinc acetate in schizophyllan having one dimensional cavity along its helical superstructure. The resultant schizophyllan/porphyrin complex generates fibrous superstructures, in which porphyrins are aligned in a chirally-twisted packing mode.
