设计并合成了一种水溶性罗丹明荧光探针RD 2。与RD 1相比，RD 2对Fe ~（3+）的选择性优于Cr ~（3+）。增强的选择性是通过将另一个配位部分的螯合部分的bridsorRD 1。生物成像研究表明，RD 2具有良好的细胞穿透性，可用于活体细胞内Fe ~（3+）的实时共聚焦成像。
A water-soluble rhodamine-based fluorescent probe (RD2) was designed and synthesized. Compared with the precursorRD1,RD2shows excellent selectivity for Fe3+over Cr3+during the detection. The enhanced selectivity was achieved by incorporating another coordination moiety to the chelating moiety of the precursorRD1. Furthermore, bioimaging studies indicated thatRD2was cell permeable and suitable for the real-time imaging of Fe3+in the living cells by confocal microscopy.
