Conjugated conducting polymers with electrochromic and fluorescent properties
We here describe recent progress in conjugated polymers research for the design of materials that present both electrochromic and fluorescent properties. We focus on the importance of electrochemical techniques as important tools for the preparation of materials deposited onto electrode surfaces through electropolymerisation and the investigation of their properties according to the applied potential in order to apply them in optoelectronic devices. The first section is devoted to a brief overview concerning structure and properties of conjugated polymers. Next, we focus on recent advances concerning the synthesis, electrochemical and optical properties of the conjugated electrochromic and fluorescent polymers. Last, we underline the possibilities of application of such materials as active layers for electrochromic devices and organic light emitting diodes (OLEDs), and also as fluorescent electrochemical sensors.
