Supramolecular device for artificial photosynthetic mimics as helix-mediated antenna/reaction center ensemble.

We have developed a novel integrated supramolecular device for a photosynthetic antenna/reaction center (RC) model based on a helical amylose, which plays an important role as the host for cyanine dye J-aggregation onto the helical surface and also for inclusion of a D-A chain chromophore inside the helical cavity, where the J-aggregates function as an array of photoreceptor antenna that funnel excitation across the helix to the chromophore.
