2-quinolyl moieties were designed and synthesized. Highly selective and significant changes in the UV–vis and fluorescence spectra of the receptors upon the addition of H2PO4– were found. In particular, receptor 3 bearing 2-quinolyl groups shows selective and nearly perfect quenching by H2PO4–, whereas 3 shows small or no fluorescence changes by another anion.
设计并合成了基于带有1-异喹啉基和2-喹啉基部分的四酰胺的新型氟受体2和3。在UV-vis和在加入H的受体的荧光光谱高度选择性和显著变化2 PO 4 -中发现。特别是,受体3轴承2-喹啉基团节目选择性的和由H近乎完美的淬火2 PO 4 - ,而3示出了小的或通过另一种阴离子无荧光的变化。
