Taking advantages of both the well-known phenazine structure and the mechanism of the supramolecular self-assembly and deprotonation process, the fluorescent and colorimetric sensor (ZL) was designed and synthesized, behaving as a circulation utilization (above 10 times) receptor for selective detection of cyanide anion (CN) in aqueous media. Upon the addition of CN, the sensor displayed obvious color changes from yellow to jacinth by naked eyes and the fluorescence immediately quenched (<10s). With respect to other common anions, the sensor possessed high selectivity and sensitivity (0.05μM) for cyanide anions. In addition, the test strips of ZL were fabricated, which could serve as practical colorimetric and fluorescent sensor for "in-the-field" measurements.
利用著名的吩嗪结构以及超分子自组装和去质子化过程的机制，设计并合成了荧光和比色传感器（ZL），它作为一种循环利用（超过10次）受体，用于在水性介质中选择性检测氰根阴离子（CN⁻）。加入CN⁻后，传感器肉眼可见地从黄色变为橙红色，并且荧光立即猝灭（<10秒）。相对于其他常见阴离子，该传感器对氰根阴离子具有高选择性和灵敏度（0.05μM）。此外，制备了ZL的测试条，其可作为用于“现场”测量的实用比色和荧光传感器。
