A rhodamine hydrazone 1 bearing coumarin moiety was designed and prepared. Compound 1 exhibited high selectivity toward Co and trivalent metal ions with fluorescence enhancement in CHOH solution. However, 1 selectively responded to Al in nearly pure HO media and was further applied to monitor Al in live cells. Moreover, 1 could also act as a colorimetric probe toward Cu in either CHOH or HO solution. In addition, sensor 1 displayed aggregation-induced ratiometric emission (AIRE) activities in mixed HO/CHOH solution.
设计并合成了一种含有香豆素部分的罗丹明腙 1。化合物 1 在 CHOH 溶液中对 Co 和三价金属离子表现出高选择性和荧光增强。然而，1 在近乎纯的 HO 介质中选择性响应 Al，进一步应用于活细胞中 Al 的监测。此外，1 还可以在 CHOH 或 HO 溶液中作为 Cu 的比色探针。另外，传感器 1 在混合的 HO/CHOH 溶液中表现出聚集诱导比率荧光（AIRE）活性。
