Graft through Sonogashira polymerization was used to functionalize various surfaces with conjugate polymers in a
dimension of less than 100 nm. Atomic force microscopy measurement revealed a dense surface coverage with several closely
packed islands. UV-vis spectroscopy and cyclic voltametry measurements suggested a moderate band gap, which is
important for various applications in material science. A device was fabricated using polymer functionalized ITO and
deposited aluminium as cathode to determine the current-voltage (I-V) characteristics and charge carrier mobility. Space
charge limited current method indicated moderate charge carrier mobility while I-V characteristic data indicated its
behaviour as semiconducting material.
