A new fluorescent NBD-polyaza-macrocycle sensor (L) was synthesized. The coordination of Cu(II) and Zn(II) in acetonitrile switches on the fluorescence with different emission wavelengths. Cu(II) complexes showed solid-state fluorescence. Both L and Cu-complex interact with human cell line (U937) highlighting the cell membrane by fluorescence microscopy.
合成了一种新型荧光 NBD-聚氮杂环传感器(L)。Cu(II)和 Zn(II)在乙腈中的配位开启了不同发射波长的荧光。Cu(II) 复合物显示出固态荧光。通过荧光显微镜观察,L 和 Cu 复合物都能与人细胞系(U937)相互作用,突出细胞膜。
