COINs are composed of semiconducting inorganic nanoparticles and organic semiconductor molecules as ligands, which are covalently coupled to the surface of the nanoparticles [1]. A well-known organic ligand is 1,2-ethanedithiol (EDT) [2]; but it has the drawback of being very short as compared to the native oleic acid ligands. In this work we study the ligand Zinc β-tetraaminophthalocyanine (Zn4APc) [3], which has a desirable length comparable to oleic acid, but a low ligand exchange behaviour. To overcome this problem, a mixture of EDT and Zn4APc has been used. The binding of the ligands are compared by morphological, electronic, optical and electrical properties.
