|Issue Date:||Sep-1999||Citation:||Ng, S.-C.,Miao, P. (1999-09). Novel functionalized polybithiophenes incorporating pendant disulfide linkers. Macromolecular Chemistry and Physics 200 (9) : 2166-2172. ScholarBank@NUS Repository.||Abstract:||Two novel thiophene derivatives, 3,3″-dithiobis(2,2′-bithiophene) and 3′,3‴-dihexyl-3,3″-dithiobis(2,2′-bithiophene), which have two 2,2′-bithiophene units linked by - S - S - bond in the 3-positions were synthesized and polymerized by chemical oxidation with FeCl3. These novel cross-linked electroactive polymers attained electrical conductivity of 0.04 S · cm-1 upon doping with iodine and displayed good thermal stability in both their doped and dedoped state. Electrochemical polymerization of 3,3″-dithiobis(2,2′-bithiophene) afforded uniform films with a high degree of conjugation exhibiting reversible electrochemical redox recycability. © Wiley-VCH Verlag GmbH, 1999.||Source Title:||Macromolecular Chemistry and Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/94381||ISSN:||10221352|
