The BOPHY fluorophore with double boron chelation: Synthesis and spectroscopy

In this review, the literature on the new fluorophore BOPHY is covered. This doubly boron-centered fluorophore resembles the well-studied BODIPY, but has its own characteristics, both in synthesis and spectroscopy. The general synthesis and properties of this fluorophore, the possibilities for postmodifications, the literature on aromatic ring-fused BOPHYs and boron substitution are discussed.
