Coupled Organic–Inorganic Nanostructures with Mixed Organic Linker Molecules

The electronic properties of semiconducting inorganic lead sulfide (PbS) nanocrystals (NCs) and organic linker molecules are dependent on the size NCs as well used ligands. Here, we demonstrate that a weakly binding ligand can be successfully attached to PbS form coupled organic–inorganic nanostructure (COIN) by mixing with strong partner. We use zinc β-tetraaminophthalocyanine (Zn4APc) in combination strongly 1,2-ethanedithiol (EDT) mixed system compare its structural, electronic, (photo-)electrical both single-ligand COINs. It is found Zn4APc assisted presence EDT leading improved film homogeneity, lower trap density, enhanced photocurrent derived devices. Thus, ligands versatile tool achieve COINs performance.
