General description
2,2′:5′,2′′-Terthiophene (TTh) may be prepared by nickel catalysed coupling reaction of grignard′s reagent derived from 2-bromothiophene and magnesium. It generates singlet oxygen. In nature, it is found in the floral extract of Tagetes minuta[1] and Echinops grijisii.[2] It is known to be toxic to mosquitoes.[1] It also exihibits antifungal activity.[2]
Application
3T can be combined with 3,4-ethylenedioxythiophene (EDOT) in a tetrabutylammonium perchlorate solution for use as an electrochromic copolymer for a wide range of applications like photovoltaics and polymer light emitting diodes (LEDs). It can also be used to form metal-organic based thin films with metals like aluminum, silver, and calcium which can potentially be used for optoelectronics based applications.
Electrochemical copolymerization of carbazole and TTh in sodium perchlorate/acetonitrile was reported. Electrochromic copolymer based on TTh and 3, 4-ethylenedioxythiophene has been reported. TTh acts as a monomer precursor for polythiophene and as a dopant for polycarbonate. It may function as a photosensitizer.
