Room temperature phosphorescent (RTP) γ-CD-CB[6]-cowheeled [4]rotaxanes were synthesized by implanting a naphthalene axle into the cavity of iodine-substituted γ-CDs. The strong green RTP was quenched exclusively by Trp while no RTP quenching was observed with other major physiological amino acids or with the Trp-containing protein HSA, demonstrating a highly specific sensing of free Trp.
室温磷光 (RTP) γ-CD-CB[6]-轮烷通过将萘轴植入碘取代的 γ-CDs 的空腔中合成。强烈的绿色 RTP 被色氨酸（Trp）特异性猝灭，而其他主要生理氨基酸或含有色氨酸的蛋白质 HSA 则没有观察到 RTP 猝灭，表明对游离色氨酸具有高度特异性的传感。
