Thiophene-based materials for electroluminescent applications

Generally, PTs are one of the most studied and important classes of linear conjugated polymers [2]. Versatile synthetic approaches to PTs, both chemical [3] and electrochemical [4], easy functionalization and unique electronic properties, which can be widely tuned, are responsible for tremendous interest on

In this chapter, we briefly introduce general synthetic approaches to PT (Section 19.2), followed by in-depth descriptions of different subclasses of light-emitting thiophene-based polymers. Starting with PT 

As already mentioned, unsubstituted polythiophene is an insoluble and infusible material. Once the polymer is prepared, it is difficult (if not impossible) to process it further as a material for electronic applications. The solubility can be greatly enhanced by the introduction of side-chains at position 3 (or at both positions 3 and 4). The most widely studied side-chains are n-alkyl substituents that can be easily introduced into the thiophene core by reaction of 3-bromothiophene with alkyl-Grignard reagents from alkyl halides [21].
