- Thin films of a conjugated polymer Poly [2-methoxy-5-(3’,7’-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO-PPV) were prepared from chloroform, 1,2dichlorobenzene and toluene solutions by spin coating technique on quartz substrates. Absorption and photoluminescence (PL) spectra of the polymer thin films prepared from different solvents were measured. The UV-vis absorption and PL spectra of MDMO-PPV films was affected by solvents used for spin coating. Further, with Atomic Force Microscope (AFM) it has been demonstrated that the surface morphology of MDMO-PPV: [6,6]-Phenyl C61-butyric Acid 3-ethylthiophene Ester thin films depends strongly on preparation condition (solvents).
