摘要

邻氨基酚和吡咯-2-羧醛的缩合产物对水介质中Fe3+和Sn2+离子的荧光传感器优于Na+、K+、Mg2+、Zn2+、Cd2+、Hg2+、Mn2+和Cr3+等金属离子。在水溶液中，Fe3+和Sn2+离子通过非结合位点与受体结合，引起强烈的荧光增强。由于受体对光诱导电子转移(PET)机制的抑制作用，可以作为过渡金属离子的荧光增强探针。

Pyrrole Based Schiff Base as a Highly Sensitive Fluorescent Sensor for Fe3+ and Sn2+ Ions

Condensation product of o-aminophenol and pyrrole-2-carboxylaldehyde behaves as a fluorescent sensor for Fe3+ and Sn2+ ions in aqueous medium over the other metal ions like Na+, K+, Mg2+, Zn2+, Cd2+, Hg2+, Mn2+ and Cr3+. In aqueous solution, Fe3+ and Sn2+ ions coordinate to the receptor through a NON binding site which induces a strong fluorescence enhancement. Receptor can be applied as fluorescence enhanced probes for transition metal ions due to the inhibition of photo induced electron transfer (PET) mechanism.
