Design and Synthesis of Nitrogen-bridged Calixarene-type Macrocycles with Extended pi-System, and Their Application as Molecular Recognition Materials

研究了新型杯芳烃类大环化合物的合成及其分子识别性能，该类化合物中芳香环通过氮原子连接，具有灵活改变电子构型的内在性质.作为最终结果，证明了本分子系统选择性地识别溶液中的钾离子和固态的二氧化碳。同时揭示了该体系的分子手性和氧化行为。

Investigated were the synthesis and molecular recognition property of novel calixarene-type macrocycles, in which aromatic rings were linked via nitrogen atoms with intrinsic nature that flexibly changes their electronic configurations. As an eventual outcome, it was demonstrated that the present molecular system selectively recognized potassium ion in solution and carbon dioxide in the solid state. Molecular chirality and oxidation behavior of the present system were also revealed.
