A new fluorescent NBD-polyaza-macrocycle sensor (L) was synthesized and studied. The coordination of Cu(II) and Zn(II) in acetonitrile switches on the fluorescence with different emission wavelengths. Crystalline Cu(II) complexes showed solid-state fluorescence. Both the free L and Cu-complexes interact with human leukemic monocyte lymphoma cell line (U937) and both are able to highlight the cell membrane by fluorescence microscopy.

Abstract
A new fluorescent NBD-polyaza-macrocycle sensor (L) was synthesized and studied. The coordination of Cu(II) and Zn(II) in acetonitrile switches on the fluorescence with different emission wavelengths. Crystalline Cu(II) complexes showed solid-state fluorescence. Both the free L and Cu-complexes interact with human leukemic monocyte lymphoma cell line (U937) and both are able to highlight the cell membrane by fluorescence microscopy.File in questo prodotto:
