Abstract: Tetracoordinate boron-based fluorescent materials have shown extensively applications in chemistry, biology and materials science owing to their unique optoelectronic properties. However, constructing chiral boron-stereogenic fluorophores through practical and universal strategies remains rare and challenging. Herein,… read more here.

Abstract: We report a boron dipyrromethene that is chiral at boron and carbon (B*C*-BODIPY) and accessible through a two-pot, one-step synthesis-an interrupted Knoevenagel condensation. The electronic circular dichroism spectra of chiral high performance liquid chromatography-resolved enantiomers… read more here.
