Novel organic-inorganic nanocomposites are synthesized by directly grafting end-functionalized conjugated polymers (CPs) onto anisotropic nanocrystals (NCs) that have a complimentary functional group through a robust Heck coupling. Such nanocomposites, in which CPs and anisotropic NCs are intimately contacted, are very promising for use in organic-inorganic hybrid solar cells with improved power conversion efficiency.
