An attempt was made to electrochemically immobilize tetrasulfonated phthalocyanine (CoTsPc) into polypyrrole in presence of three types of surfactants (cationic, anionic, and neutral) during the polymerization of pyrrole in an aqueous solution with different potential regions. The surface characteristics of anodically/cathodically prepared electrodes with cetyltrimethylammonium bromide (CTAB), sodium...
5,2′-5′,2″-Terthiophene-3′-carboxylic acid (TTCA), a potentially useful starting material for the synthesis of functionalized polyterthiophenes, can be simply prepared by the treatment of 3′-bromothiophene with CuCN in DMF followed by hydrolysis in KOH-ethoxyethanol. TTCA was polymerized on a glassy carbon electrode in a 0.1M Et 4 NClO 4 /dichloromethane solution. The polymer film...
