合成了一种新的基于三联苯的双功能荧光化学传感器3a，该传感器展示了在两种对比模式下对Cu2+和F-离子的选择性光学识别。在测试的各种阳离子和阴离子中，该化合物对 Cu2+ 离子表现出高度选择性的“开-关”可切换行为，对 F- 离子表现出“开-关-开”行为。化学传感器对 Cu2+ 和 F- 离子的检测限分别为 100 nM 和 10 nM。 (C) 2010 Elsevier Ltd. 保留所有权利。
A new terphenyl based bifunctional fluorescent chemosensor 3a has been synthesized, which demonstrates selective optical recognition of Cu2+ and F- ions in two contrasting modes. The compound shows highly selective 'On-Off' switchable behavior toward Cu2+ ions and 'On-Off-On' behavior toward F- ions among various cations and anions tested. The detection limits of chemosensor for Cu2+ and F- ions are found to be 100 nM and 10 nM, respectively. (C) 2010 Elsevier Ltd. All rights reserved.
