An Imidazo[1,5-a]pyridine Benzopyrylium-Based NIR Fluorescent Probe with Ultra-Large Stokes Shifts for Monitoring SO₂.

ABSTRACT: A mitochondria-targeted NIR probe based on the FRET mechanism was developed. It shows ultra-large Stokes shifts (460 nm) and emission shifts (285 nm). Furthermore, we also realized the imaging of SO₂ in living SKOV-3 cells, zebrafish and living mice which may be useful for understanding the biological roles of SO₂ in mitochondria and in vivo.
