Synthesis and electrochemical polymerization of N-ethylcarbazole-bis-3,4-etyhlenedioxythiophene-N-ethylcarbazole comonomer

摘要

A new comonomer ECz-BEDOT-ECz (EBEE) [ECz: N-ethylcarbazole-BEDOT:2,2'-bis(3,4-ethyhlenedioxy) thiophene] has been synthesized, characterized, and electro-polymerized on Pt and carbon fiber microelectrodes (CFME). The ECz side group of the comonomer plays an important rote in determining its physical properties PEBEE and it resembles the behavior of corresponding homopolymer (PECz). PBEDOT was increased by the incorporation of ECz monomer into structure. The environmental stability of PBEDOT was increased by incorporating the ECz unit into the structure. The new comonomer seems prefer to be electrode-posited onto CFME as opposed to Pt. (c) 2006 Wiley Periodicals, Inc.
