Abstract

Two new boron-based conjugated compounds 1 and 2 containing one and three monopyrrolo-annelated tetrathiafulvalene (TTF) unit(s) were synthesized and characterized. They exhibit typical ICT absorptions which can be modulated after addition of fluoride ion. In addition, the oxidation potentials of 1 and 2 are shifted to low potential region in the presence of fluoride ion. Such absorption spectral and electrochemical responsiveness of 1 and 2 toward fluoride ion is due to the binding of the boron units with fluoride ion.

摘要

两个新的硼基共轭化合物 1 和 2 分别含有一个和三个单吡咯并[3,4-b]噻吩并[2,3-d]噻吩单元，已被合成并得到了表征。它们具有典型的 ICT 吸收，加入氟离子后可以进行调节。此外，在氟离子存在的情况下，1 和 2 的氧化电位向低电位区域移动。1 和 2 对氟离子的这种吸收光谱和电化学响应归因于硼单元与氟离子的结合。
