The photoconductivity of undoped as well as nanostructures of gold chloride doped hexa-alkoxytriphenylene series (HAT4, HAT5 and HAT6) has been studied. After doping with gold chloride, the photoconductivity increased by more than ten times for HAT4 and HAT5 and not for HAT6. The high photoconductivity can be explained in terms of the transition temperatures, the core-core distances and their length of side chains. Photoconductivity of the gold chloride doped hexa-alkoxytriphenylene derivatives are in the region 10(-4)-10(-5) Sm-1, which are five orders of magnitude higher than that of undoped compounds. The high NIR absorbance combined with the photoconductivity makes this nanocomposite a potential candidate for organic solar cell applications. (C) 2012 Elsevier B.V. All rights reserved.
