Various polymeric blends of hole transporting materials, (such as MEH‐PPV and P3HT) and electron transporting materials (such as poly(phenyl‐vinyl‐quinoline) and poly[2‐(4‐methacryloxyphenyl)‐5‐phenyl)‐1,3,4‐oxadiazole]) have been prepared and investigated. Moreover a soluble, main chain oxadiazole bearing polyether has been synthesized, aiming towards an efficient electron transporting polymeric material which was also used for blend preparation together with P3HT. A deeper investigation into their spectroscopic characteristics using, primarily, FT‐IR spectroscopy, but also UV‐Vis spectroscopy has been conducted. The surface morphology of these blends was investigated using Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) in an attempt to gather information for their solid state properties and morphologies. Finally, DSC measurements provided additional insight into the thermal behaviour of these materials.
