Based on RhodamineB, two Al3+/Cu2+-selective chemosensors were synthesized, which display a high selectivity for Al3+ and Cu2+ among environmentally and biologically relevant metal ions. A 1,8-Naphthyridine modified rhodamine derivative can detect Al3+ in ethanol with off–on fluorescence behavior, and detect Cu2+ in aqueous solution with colorimetric method. The 8-Hydroxyquinoline-based rhodamine sensor
基于罗丹明B,合成了两个Al 3+ / Cu 2+选择性化学传感器,在环境和生物相关的金属离子中,Al 3+和Cu 2+具有很高的选择性。1,8-萘啶修饰的若丹明衍生物可以检测乙醇中的Al 3+,具有不连续的荧光特性,并且可以使用比色法检测水溶液中的Cu 2+。基于8-羟基喹啉的若丹明传感器可以检测Al 3+在乙醇中使用关闭式荧光法和比色法。由于形成金属络合物,检测机制涉及开环过程。Job的图和飞行时间质谱研究表明,每个化学传感器都以1:1的化学计量比螯合了Al 3+ / Cu 2+。该化学传感器的结合和Al 3+ /铜2+在化学上是可逆通过添加的F - / EDTA溶液,分别。

A novel fluorescent sensor bearing a quinoline and an anisidine moiety has been developed for highly selective detection of Fe3+, which shows photo‐induced electron transfer (PET) behavior induced by Fe3+. Binding of Fe3+ to the sensor induced the electron of C = N group transfer from quinoline to iron, the result exhibits fluorescent enhancement. With the features of easy synthesis, simple structural

By utilizing the quinolinic derivative, 8-carboxymethoxy-2-carboxylicquinoline (L), five transition metal coordination complexes, [M(L)(H2O)3]·H2O] (M = Mn (1), Co (2)), [Ni(L)(H2O)2] (3), and [M(L)](H2O)}n (M = Ni (4), Cu (5)), were synthesized by hydrothermal methods employing similar synthetic strategies. The crystal structures, magnetism and high-field EPR were characterized for the obtained compounds
