  Electrochemical Synthesis of C₆₀-Derivatized Poly(thiophene)s from Tailored Precursors

  摘要：

  New series of C-60-derivatized bithiophenic precursors with low oxidation potential have been synthesized using the thiolate deprotection chemistry. The analysis of the electropolymerization of these compounds shows that the use of two-site precursors leads to polymers combining enhanced conjugation length, faster switching time, and improved stability under redox cycling. The unsuccessful attempts to identify the optical signature of the reduced forms of the attached C-60 by spectroelectrochemistry suggest that the PT backbone is unstable in the presence of the C-60 anion radical. Preliminary photoelectrochemical experiments on films deposited on platinum electrode reveal a significant enhancement of the photocurrent for the C-60-derivatized polymer when compared to a nonsubstituted reference polymer, indicating that these new materials are potentially useful for photovoltaic energy conversion.

  Electrogenerated poly(thiophenes) derivatized by bipyridine ligands and metal complexes

  摘要：

  The synthesis of a series of bithiophenic precursors of electrogenerated conjugated polymers functionalized by bipyridine ligands is described. The precursor structure involves two polymerizable groups attached at both ends of a bipyridine ligand and fixed at an internal beta-position of thiophene via an alkylsulfanyl or alkoxy spacer. Electrochemical and optical data show that the low polymerization potential resulting from the association of 3,4-ethylenedioxythiophene (EDOT) and alkylsulfanyl or alkoxy thiophene combined with the multi-site polymerization approach allows a straightforward electrosynthesis of extensively conjugated and stable functionalized polymers. On the basis of these results, iron and ruthenium complexes of these precursors have been synthesized and electropolymerized. The analysis of the electrochemical behavior of the resulting polymers shows that they exhibit the typical electrochemical signature of both the conjugated polythiophene backbone and the immobilized metal complex.
