General description
2,2′:5′,2′′-三噻吩（TTh）可通过衍生自2-溴噻吩的格氏试剂和镁的镍催化偶联反应而制备。它可产生单线态氧。在自然界中，存在于印加孔雀草和Echinops grijisii的花卉提取物中。已知它对蚊子有毒。它还具有抗真菌活性。
Application
咔唑和TTh在高氯酸钠/乙腈中的电化学共聚合已被报道。基于TTh和3,4-亚乙二氧基噻吩的电致变色共聚物已被报道。TTh可充当聚噻吩的单体前体以及聚碳酸酯的掺杂剂。它可用作光敏剂。
在四丁基高氯酸铵溶液中，3T可结合 3,4-乙烯二氧噻吩 (EDOT)，作为电致变色共聚物用于各种应用，如光伏发电和聚合物发光二极管 (LED)。它也可以和铝、银和钙等金属一起形成金属有机物薄膜，用于光电子学应用等。
