    (International Journal of Applied Chemistry, 2016) Amirah Nabilah Rashida; Rafizah Rahamathullaha; Wan M. Khairula
    Works on conjugated molecules comprising of acetylide and thiourea moieties mimicking the function as macro devices are surprisingly not widely explored even though this system is proven to be an excellent candidate in various molecular electronic applications. They individually offers electronic delocalization in extended π-orbital system that contributes in electrical conductivity. Due to these concerns, a novel acetylide-thiourea derivative namely N-(3,5-dimethoxy benzoyl)-N’-(4-(phenylethynyl)phenyl) thiourea (DBPT) was successfully designed, synthesized and characterized via CHNS, IR, UV-Vis, 1H and 13C NMR, TGA and Cyclic Voltammetry (CV). The active layer of DBPT was deposited on ITO substrate via electrochemical deposition method (ECD) and then its conductivity was evaluated by using Four-Point Probe. The electrical conductivity test showed that the film formed has an ability to conduct electricity up to 0.2008 Scm-1 under maximum light intensity of 150 Wm-2. Therefore, it is undoubtedly that the proposed single molecule of acetylide-thiourea has displayed a good performance to act as conductive film as well as has provided a great interest for a new field of research topic to be explored in diverse application
