Abstract

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.
