Star-shaped Thiourea Derivative as Single Molecule Conductive Thin Film

Abstract

The electronic delocalization in extended π-orbital system of conjugated organic molecules brings significant contribution and has lead for further investigation to exploit this system to be used as potential conductive thin film. In this work, a star-shaped thiourea, N1,N3,N5-tris(4- (nonyloxy)phenyl)-N’-(benzene-1,3,5 tricarbonyl) thiourea (STU) based on Donor(D)-π-Acceptor(A) system was successfully synthesized from continuous reactions of intermediate compound 4- nonyloxy aniline hydrochloride with benzene-1,3,5-tricarboxylic acid chloride prior to form active substrate in the form of film. These compounds were characterized via several spectroscopic and analytical methods namely IR, UV-Vis, CHNS elemental analysis, 1H and 13C NMR as well TGA
