A new class of alkyl-chain-appended pyrene derivatives 4-14 were synthesized and evaluated for their gelation abilities. Depending on the nature of the linking group, these compounds gelated a number of organic solvents, either in the presence or in the absence of the acceptor molecule 2,4,7-trinitrofluorenone (TNF). Compounds with ester, ether, or alkyl linkages gelated a number of hydroxylic and
合成了一类新的烷基链附加的derivatives衍生物4-14,并评估了它们的胶凝能力。根据连接基团的性质,这些化合物在存在或不存在受体分子2,4,7-三硝基芴酮(TNF)的条件下会胶凝许多有机溶剂。具有酯,醚或烷基键的化合物通过与TNF的电荷转移相互作用而胶凝许多羟基和烃类溶剂,而具有酰胺,氨基甲酸酯和尿素接头的化合物则通过多种溶剂在各自的溶剂中自行形成凝胶π-π堆积和氢键相互作用。氨基甲酸酯(S)-12的X射线晶体结构显示出氢键和堆积特征,如模型所暗示。
