A new sandwich-tpype dilutetium tetraphthalocyanine 4 has been synthesized by the reaction of dimeric lutetium(III) phthalocyanine 3 with two equiv. of dilithium octakishexylthiophthalocyanine in amyl alcohol. Compound 3 was prepared from 4′,5′,4″,5″-tetraiminoisoindoline(1,4,7,10-tetrathia-12-crown-4) 1, 4,5-bis(hexylthio)-1,2-diiminoisoindoline 2 and lutetium acetate in amyl alcohol. Compounds 3 and 4 were characterized by elemental analysis, UV/visible, IR, 1H NMR and ESR spectroscopy. The electrochemical and electrochromic properties of 3 and 4 have been examined by cyclic voltammetry. Both 3 and 4 displayed well-defined electrochromic behavior.
通过二聚镥(III)酞菁3与2当量的反应,合成了一种新型夹心型稀四酞菁4。戊醇中的八己基硫代酞菁二锂。化合物3由4',5',4",5"-四亚氨基异吲哚啉(1,4,7,10-四硫基-12-冠-4) 1, 4,5-双(己硫基)-1,2-制备二亚氨基异吲哚啉 2 和乙酸镥的戊醇溶液。通过元素分析、紫外/可见光、红外、1H NMR 和 ESR 光谱对化合物 3 和 4 进行了表征。 3和4的电化学和电致变色性质已通过循环伏安法进行了检查。 3 和 4 都表现出明确的电致变色行为。
