Abstract:
Organic nanostructures have attracted the attention of both scientific as well as academic community due to their structure related chemical and semiconducting properties. While
nanostructures of inorganic materials and metal oxides have been the center of attraction for many years, organic nanostructures of I conjugated molecules have several advantages over the inorganic counterparts, such as unlimited choices of molecular structures for property optimization, high flexibility, low cost of materials fabrication, ease for large area processing and compatibility with flexible and lightweight plastic substrates, thus opening broader scope for molecular electronic devices. In this direction, 1D nanowires (NWs) of Cu (II) 1,4,8,11,15,18,22,25-octabutoxy-29H,31H-phthalocyanine molecule have been grown onto glass substrate by cost effective solution processing technique. The density of NWs is found to be dependent on the concentration of solution and exposure time. These nanowires have been characterized by XRD, SEM and UV-Visible absorption spectroscopy. The conductivity of nanowires has found to be more than that of spin coated film. The possible formation mechanism of these structures is I-I interaction between phthalocyanine molecules. Although phthalocyanine nanostructures have been grown by OMBE, OPVD, thermal evaporation techniques with limitation of higher cost of fabrication but these nanowires with long range order, low fabrication cost and improved conductivity indicate their potential for molecular device applications.
