摘要: A water soluble Lemke chromophore derivative shows an unusual polarity dependence of its emission efficiency, leading to strong red-NIR fluorescence in when fitted with appropriate water-solubilizing polymer chains. In this edge article, the synthesis is described. The on solvent investigated experimentally and rationalized basis ab initio calculations. Finally, we demonstrate that a valuable candidate for vivo two-photon imaging cerebral vasculature, absorption biological transparency window.
