A series of fluorescent sensors based on 8-hydroxyquinoline dansylate as core and dendritic PAMAM as shell were synthesized. Their fluorescence characteristic and fluorescent sensing behavior toward metal ions were studied in water/methanol (1: 1, v/v). The sensors exhibit good selectivity and sensitivity for Fe(3+) ion and to some extent for Cr(3+) ion. The third generation dendrimer has the better sensitivity than the first and second generations.
合成了一系列以 8-羟基喹啉丹酸酯为核、树枝状 PAMAM 为壳的荧光传感器。研究了它们在水/甲醇（1:1，v/v）中的荧光特性和对金属离子的荧光传感行为。这些传感器对 Fe(3+)离子具有良好的选择性和灵敏度，对 Cr(3+)离子在一定程度上也具有选择性和灵敏度。第三代树枝状聚合物比第一代和第二代具有更好的灵敏度。
