SBDIPY Chromophores as Multitools for Molecular Sensing

We herein report a Lewis acid and a Lewis base responsive antimony dipyrrin complex suitable for both nuclear magnetic resonance and photoluminescence spectroscopy detection. The complex showcases distinct reaction modes that go along with a boost or depletion of fluorescence emission. Furthermore, we disclose a correlation between spectroscopic data and solid-state structural parameters in a rare set of 1:1 halogen-bridged Sb-dipyrrin adducts.
