甲基氮杂杯[4]吡啶(MACP-4)是一种具有独特构象和空穴结构的高效大环主体分子，它能选择性地识别锌离子，在固相和溶液中都能形成稳定的锌(II)-MACP-4络合物，结合常数高达5.97(LogKs)。用光谱滴定和X射线分析研究了锌(II)-MACP-4络合物对不同几何构型的氨基酸和阴离子的分子识别作用。锌(II)-MACP-4络合物识别17种氨基酸，结合常数达3.97(LogKs)。另一方面，锌(II)-MACP-4络合物选择性地与阴离子相互作用，最大缔合常数为3.9(LogKs)。
As a powerful macrocyclic host molecule with unique conformation and cavity structure that are fine-tuned by the bridging nitrogen atoms, methylazacalix[4]pyridine (MACP-4) has been shown to selectively recognize Zn2+ and form stable Zn(II)-MACP-4 complexes both in solid state and solution with an association constant up to 5.97 (logKs). The molecular recognition of Zn(II)-MACP-4 complexes towards various amino acids and anions with different geometry was investigated by using the spectral titration methods and X-ray analysis. The Zn(II)-MACP-4 complex was found to recognize the 17 amino acids tested with the association constant up to 3.97 (logKs). On the other hand, the Zn(II)-MACP-4 complex selectively interacted with anions and the maximum association constant of 3.9 (logKs) was obtained.
