Synthesis, Characterization, Morphology and Photovoltaic Properties of Aniline-Tiophene Based Polymers

Abstract :

Monomers composed of thiophene and aniline rings, 4-(2-thiophen)aniline and 4-(3-thiophen)aniline, were successfully synthetized through the Suzuki-Miyaura cross coupling reaction and then polymerized. The polymers poly 4-(2-tiophen)aniline and poly 4-(3-tiophen)aniline (P4,2TA and P4,3TA) were characterized via spectroscopycal NMR, optical and electrochemical methodologies. Subsequently the morphology of deposits were characterized using atomic force microscopy (AFM) and X-ray diffraction (XRD). The photovoltaic devices were constructed under the same conditions, observing differences in the photovoltaic yield of each polymer. P4,2TA exhibited higher photovoltaic yield in comparison with P4,3TA, indicating that the molecular geometry affects the crystallinity and surface morphology of the polymeric deposits, and the photovoltaic properties
