    SUPRAMOLECULAR SOLAR CELLS VIA CRYSTAL ENGINEERING OF FULLERENES

    Fullerene and its derivatives exhibit extraordinary electrical properties suitable for photovoltaic applications and are expected to lead to next-generation plastic solar cells. Key to their development as photovoltaic materials is the ability to organize them into supramolecular structures beyond the molecule that orchestrates the conversion of light into electrical potential and electricity. Dynamic crystals are solids with structures capable of undergoing crystal-to-crystal transformations in which the crystalline phase acts as a solvent in innovated solid-solutions suitable for a wide variety of applications in environmental sustainability. We synthesized and characterized a set of closely related amphiphillic molecules based on 1-alkyl pyridinum bromide salts and studied their single-crystal-to-single-crystal transformation properties in which the bromide ion exchanges with exogenous anions such as oxoions as well as anionic fullerenes that exhibit photovoltaic properties. X-ray powder diffraction, inductive coupled plasma (ICP), NMR analysis, and UV-vis spectroscopy were used to study the crystal dynamic behavior of the materials and will be presented. Phenyl-C61-butyric acid methyl ester and its properties will be applied via pi pi stacking and ionic bonding from the negatively charged PCBA and the positively charged alkylated chain.
