A quinoline functionalized pillar[5]arene, QPA has been prepared and its interaction with biologically relevant ions and molecules in aqueous solution has been demonstrated. The sensor molecule, QPA has shown selectivity towards Fe among eleven metal ions studied. The Fe complex of QPA (FeQPA) selectively interacts with F among halides by ∼4 fold fluorescence enhancement. Further, FeQPA has shown selectivity towards arginine and lysine among twenty naturally occurring amino acids. The binding of QPA with Fe has been confirmed by MALDI-TOF and H NMR titrations.
一种喹啉功能化的[5]轮烷（pillar[5]arene），QPA，已经被制备出来，并在水溶液中证明了其与生物相关离子和分子的相互作用。传感分子 QPA 对所研究的 11 种金属离子中的 Fe 表现出选择性。Fe 与 QPA 的配合物（FeQPA）通过约 4 倍的荧光增强选择性地与卤化物中的 F 相互作用。此外，FeQPA 对 20 种天然氨基酸中的精氨酸和赖氨酸表现出选择性。QPA 与 Fe 的结合通过 MALDI-TOF 和 1H NMR 滴定得到了证实。
