Abstract
In this paper, novel azo-substituted polythiophene derivatives, poly[4-((4-(phenyl)azo)phenoxy)butyl-3-thienylacetate] (PATh-4) and the copolymer of 3-hexylthiophene and 4-((4-(phenyl)azo)phenoxy)butyl-3-thienylacetate (COP64) were synthesized. The structure and photo-electronic behavior of both polythiophene derivatives were characterized by NMR, FT-IR, UV-Vis, XRD, GPC and photoluminescence spectroscopy. The results showed that the azo photoactive side chains not only modify their own UV-Vis absorption but also affect the photoluminescent features associated with the polythiophene conjugated backbone. This indicates that the photoluminescent properties of polythiophene derivatives can be modified through a photo-induced isomerization (trans-cis) reaction of azo chromophores in the side chains.
