Hierarchically organized superstructure emerging from the exquisite association of inorganic crystals, organic polymers, and dyes: A model approach towards suprabiomineral materials

We report a novel hierarchially organized superstructure emerging from an exquisite association of inorganic crystals, polymers and dyes. The resultsnt K2SO4 /poly(acrylic acid) composite includes five different tiers from nanoscopic to the macroscopic. An additional new tier leading to functionality is formed by the incorporation of organic dyes that are organized in a nanospace. The emergent superstructure and properties are designed through changes in polymer concentration. The multiple roles of the polymer realize the generation of the architecture at each size scale. This model approach should be widely applicable to other systems allowing for the preperation of innovative materials by an appropriate combination of crystals polymers, and functional molecules.
