Two new tetracationic cyclophanes 1 and 2 containing tetraphenylethene and bipyridinium moieties were synthesized via a two-step SN2 reaction. These water-soluble cyclophanes with a cationic and hydrophobic cavity exhibited selective recognition for amino acids (e.g. tryptophan) and adenosine derivatives (e.g. ATP) via electrostatic and π-π interactions in water.
两个新的四价阳离子环芳烃 1 和 2 通过两步 SN2 反应合成，含有四苯乙烯和联吡啶部分。这些水溶性的带有正电荷和疏水性空腔的环芳烃在水中通过静电和π-π相互作用对氨基酸（如色氨酸）和腺嘌呤衍生物（如 ATP）表现出选择性识别。
