Descrizione generale
2,2′:5′,2′′-Terthiophene (TTh) may be prepared by nickel catalysed coupling reaction of grignard′s reagent derived from 2-bromothiophene and magnesium.[1] It generates singlet oxygen.[2] In nature, it is found in the floral extract of Tagetes minuta[3] and Echinops grijisii.[4] It is known to be toxic to mosquitoes.[3] It also exihibits antifungal activity.[4]
Applicazioni
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[5] and polymer light emitting diodes (LEDs).[6][7] 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.[8]
Electrochemical copolymerization of carbazole and TTh in sodium perchlorate/acetonitrile was reported.[9] Electrochromic copolymer based on TTh and 3, 4-ethylenedioxythiophene has been reported.[10] TTh acts as a monomer precursor for polythiophene[11] and as a dopant for polycarbonate.[12] It may function as a photosensitizer.[13]
