A series of β-hydroxy-vinylimine boron compounds 1-7 have been reported to exhibit unique dual emission, consisting of fluorescence and room temperature phosphorescence (RTP) in solution. This finding triggered intensive research of RTP in β-hydroxy-vinylimine boron derivatives. Herein, we show clear evidence that the associated dual emission, especially RTP, is caused by the experimental artifact, where bright emission intensity saturates the detection dynamic range of the fluorimeter.
