Anti-quenching NIR-II molecular fluorophores for in vivo high-contrast imaging and pH sensing
Nature Communications, 2019 Fluorophores operating in the second near-infrared window suffer from solvatochromism-caused fluorescence quenching in biological aqueous solution. Here, the authors synthesized a series of pH-responsive pentamethine cyanine fluorophores that afford ...

Solvatochromism and electrophilicity
Chemical Physics Letters, 2011 Abstract Solvatochromic dyes that exhibit a negative or a positive behaviour may be distinguished and their solvatochromism predicted with the aid of DFT-based indices, such as their electrophilicity ω , hardness η and by the Fukui electrophilic functions f G + of the donor and acceptor moieties of the molecule, calculated in the ...
