of organogels. Considering the results, we concluded that compounds were ‘super gelators’. Interestingly, the gelators reacted with 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane to form charge-transfer (CT) complexes and binary organogels. 1HNMR and FT-IR revealed that cooperation of hydrogen bonding, π–π and CT interactions was the main driving force for formation of the native and CT gels.
摘要合成并表征了一系列新的四硫富瓦烯基有机凝胶剂,其具有四个结合酰胺基团的疏水链。用有机溶剂如环己烷、四氯化碳和氯苯得到所得透明有机凝胶。此外,烷基链的长度影响了有机凝胶的凝胶化能力。考虑到结果,我们得出结论,化合物是“超级凝胶剂”。有趣的是,凝胶剂与 2,3,5,6-四氟-7,7,8,8-四氰基醌二甲烷反应形成电荷转移 (CT) 复合物和二元有机凝胶。1HNMR 和 FT-IR 表明氢键、π-π 和 CT 相互作用的协同作用是形成天然凝胶和 CT 凝胶的主要驱动力。天然干凝胶的扫描电子显微镜图像揭示了三维交联网络的特征凝胶形态,而 CT 复合干凝胶的形态显示出无定形棒状聚集体。X射线电...
