Activity-based sensing of CO through palladium-mediated carbonylation. (a) CO detection with the BODIPY-based palladium complex COP-1. (b) Fluorescence spectra of 1 μM COP-1 in the presence of 50 μM CORM-3 over 120 min (red trace). (c) Confocal images of HEK293T cells stained with 1 μM COP-1 at 37 °C for 30 min. The bar graph presents mean fluorescence intensities, with error bars representing the standard error of the mean (SEM) (n = 3). Adapted from ref 27. Copyright 2012 American Chemical Society.
