  Guest-responsive intramolecular charge transfer of viologen–crown ether conjugate

  摘要：

  Viologen-benzocrown ether conjugate (1) was prepared, in which a phenyl unit in benzocrown ether was incorporated into the nitrogen atom of a bypiridinium unit through a sigma bond. 1 showed a yellow color associated with an intramolecular charge transfer (CT) that responds to alkali and alkaline earth metal ions, especially to Ca2+.

  A new guest-responsive color-change host, 1, in which three benzocrown ethers modified with bipyridinium are connected through the mesitylene unit, was synthesized to investigate its ion-recognition ability. 1 exhibited a yellow color associated with an intramolecular charge-transfer (ICT) absorption, which faded upon the addition of alkali and alkaline earth metal ions. Ba2+ was detected by 1 with high sensitivity.

  为了研究其离子识别能力，我们合成了一种新的客体响应变色宿主 1，其中三个用联吡啶修饰的苯并冠醚通过间二甲苯单元连接在一起。1 显示出与分子内电荷转移（ICT）吸收相关的黄色，在加入碱金属和碱土金属离子后，黄色会褪去。1 对 Ba2+ 的检测灵敏度很高。
