Abstract

Two BODIPYs and one boron beta-diketonate were threaded through a macrocycle bearing a 2,2’-biphenol unit, showing thus the ability of boron to act as a gathering atom. The new threaded species were characterized by 1D and 2D NMR spectroscopy as well as by X-ray crystallography for one of them. The BODIPYs exhibited interesting fluorescence features with quantum yields up to 91% and enhanced photostability compared to their non-threaded homologues.
