Photophysical Properties of Polythiophenes

Polythiophenes (PT) have been exploited over the past several years due to their structural versatility and optical properties upon functionalization to the thiophene main chain (Jen et al., 1986; Sato et al., 1986). Its structure of C atoms may be compared as a modification of trans polyacetylene w...

More Information
Summary:Polythiophenes (PT) have been exploited over the past several years due to their structural versatility and optical properties upon functionalization to the thiophene main chain (Jen et al., 1986; Sato et al., 1986). Its structure of C atoms may be compared as a modification of trans polyacetylene with a more complicated organization due to the bond with sulfur atom forming a ring, as shown in Figure 5.1. This modification becomes PT stable under atmospheric and thermal exposure, beyond the possibility of tuning crystallinity and solubility through functionalization (Springborg, 1992).
