stimulus responses on various external stimuli, including temperature, sonication, anions and K+. This gel could be transformed into the charge transfer salt gel with I2, which was an important first example of the charge transfer salt gel of TTF with I2 in solvents. The same gel-gel transition was also induced by adding other inorganic oxidants (i.e., Ag+, Fe3+, Cu2+ and TFA) and π-electron acceptors (i.e
由电子给体四硫富瓦烯和电子受体卤素形成的电荷转移盐已成为构建高电导率超分子纳米材料的重大关注焦点。但是,TTF-X 2组合的稳定的超分子凝胶系统具有可控的自组装途径,在溶剂中无法轻易获得。在这种情况下,根据冠醚-单吡咯并四硫富瓦烯-1-谷氨酰胺三联体构建了新颖的代表性有机凝胶体系。形成的凝胶在各种外部刺激(包括温度,超声,阴离子和K +)上表现出多种刺激响应。该凝胶可以用I 2转化为电荷转移盐凝胶,这是TTF与I 2在溶剂中的电荷转移盐凝胶的重要第一个例子。通过添加其他无机氧化剂(即Ag +,Fe 3+,Cu 2+和TFA)和π电子受体(即TCNQ和C 60)也诱导了相同的凝胶-凝胶转变。
