In this work, we have fabricated nano-scale hybrid systems from polythiophene LB ultra thin film assembly with incorporated Au nanoparticles (AuNP). Investigation of electronic properties such as oxidation potential, conductivity and the electron mobility showed increase in measured parameters with increase in number of layers. Blends of an amphiphilic regioregular, ether-terminated polythiophene with a poly alkyl thiophene were also employed. Interaction studies showed that a net repulsive force exists between the two thiophene species – making the film assemblies potential candidates for patterned incorporation of AuNP. A number of interesting phenomena in terms of affinity of AuNP for thiophenes were observed by the various microscopic and spectroscopic characterization techniques. Electronic properties were investigated using Hall and surface resistivity measurements. A significant enhancement was observed in the conducting properties upon incorporation of AuNP.
