Abstract
A series of new fluorescent probes bearing tren-spaced rhodamine B and dansyl groups have been synthesized. Compound 1 exhibits selective changes in the absorption and the emission spectra toward Cu2+ ion over miscellaneous metal cations. Among 1-3, 1 shows the best FRET efficiency through dansyl emission to rhodamine absorption for the Cu2+ ion.
摘要
一系列带有三乙撑四胺间隔的罗丹明B和丹磺酰基团的新型荧光探针已被合成。化合物1对Cu2+离子相对于其他金属阳离子在吸收光谱和发射光谱上表现出选择性变化。在1-3中，对于Cu2+离子，1通过丹磺酰发射到罗丹明吸收显示出最佳的荧光共振能量转移效率。
