摘要
合成了一种新型芘基荧光化学传感器(芘-1-甲基)- l -缬氨酸(1)。1是一种高选择性的化学传感器，通过荧光猝灭来检测Cu(II)离子，并表现出基于水的有机溶剂凝胶性。棒状表面形貌可能是由于分子间羧酸基团之间的氢键和芘部分的π-π堆积所致。此外，1也可用于天然水样中Cu2+离子的实际检测。
A luminescent pyrene-valine conjugates for the detection of copper (II) ions in aqueous media
A novel pyrene-based fluorescent chemosensor (pyren-1-ylmethyl)-L-valine (1) has been synthesized. 1 is a highly selective chemosensor for detecting Cu(II) ions through fluorescence quenching over other competitive metal ions and showing aqueous-organic solvent-based gelation properties. Rod-shaped surface morphology may be attributed to intermolecular Hydrogen bonding between the carboxylic acid group and π-π stacking of pyrene moiety. In addition, 1 can also be utilized for the practical detection of Cu2+ion in natural water samples.
