在4,13-二氮杂-18-冠醚的两个胺侧分别连接两个罗丹明B基团,合成了一种罗丹明B荧光传感器,在甲醇-水(3:2,v/v,pH7.2)溶液和活细胞中作为高灵敏的Cr ~(3+)荧光探针。
A rhodamine B-based sensor consisting of two rhodamine B moieties linked to the two amine sides of a 4,13-diaza-18-crown-6 ether was synthesized as a highly sensitive fluorescent probe formonitoring Cr3+ in a MeOH-H2O (3 : 2, v/v, pH 7.2) solution and in living cells.
