An Unexpected Boron Rearrangement Leads to a Fluorogenic and Colorimetric BODIPY Probe

摘要

The isolation and characterization of a kinetically stable oxadiazaborinine(ODB) dye are described, which undergoes an unexpected thermal boronrearrangement with a color change and increase in fluorescence. This controllablereaction allows for the use as a practical time-temperature indicatorprobe with the advantages of photostability, non-reversibility, and environmentalfriendliness.
