|Title:||Current Synthetic Methodologies For Semiconducting Polymers|
dos Reis L.A.
|Abstract:||Since the publication of pioneering work in the 1970's, which described and evaluated conducting polymers, the preparation of precisely substituted polymers for the purpose of obtaining materials with tuned electrical and mechanical properties has seized great attention from the scientific community. The arsenal of synthetic methodologies available to access archetypal or tailored polymer structures can be either wide or limited depending upon the nature of the desired monomer. These type of materials include polyacetylene itself or its related poly(hetero)arylenevinylenes analogues and the major synthetic approaches towards polymer synthesis comprise Ullmann, Heck or Wittig type reactions, olefin metathesis, aldol condensation and, of course, electrochemical polymerizations. The regio- and chemoselectivity of these methodologies will be discussed here with special emphasis covering synthetic approaches to homopolymer preparation, although some of these reactions can be effectively used to prepare different types of copolymers. © 2013 Nova Science Publishers, Inc.
