摘要
2,3,6,7-四(2′-氰乙硫基)四硫富瓦烯在醇钠的作用下消除氰乙基生成四硫富瓦烯四硫盐,再与9-溴甲基蒽反应生成四(9-亚甲基蒽硫基)四硫富瓦烯,通过氧化还原法发现其荧光能够可逆地增强或减弱,因此它是一个新的氧化还原荧光开关。在多种金属离子中,该新型氧化还原开关只对Fe3+有识别性能,其荧光强度随Fe3+的量增大而增强,其他金属离子没有干扰。所以,它又是一种对Fe3+具有高选择性识别的荧光传感器。该文报告工作的新颖性已为安徽大学图书馆2009年4月30日出具的第2009006号《科技查新报告》所证实。
2,3,6,7-Tetrakis（2′-cyanoethylthio）tetrathiafulvalene was treated with sodium ethoxide to deprotect 2-cyanoethyl,affording tetrathiafulvalene tetrathiolate.The generated tetrathiolate was trapped by 9-bromomethylene anthracene to yield tetrakis（9-methyleneanthracenethio） tetrathiafulvalene.Its fluorescence can be reversibly modulated by the sequential electrochemical oxidation and reduction.So it is a new redox fluorescence switch.It may highly selective detect Fe^3＋ in the presence of many metal ions.The fluorescence intensity increased with the increasing amounts of Fe^3 ＋. Therefore, it is a novel highly selective fluorescence sensor, too. The novelty of the reported work in this paper was proved by No. 2009006 science and technology novelty checking＇s report issued by library of Anhui University on April 30,2009.
