Chiroptical behavior of BINOL-based spiranic <em>O</em>-BODIPYs. A study on the influence of the structural factors

Abstract

Abstract:Spiranic O-BODIPYs bearing a phenol-based bi(polyarene) unit tethered to the boron center through oxygen atoms constitute an interesting family of BINOL-BODIPY dyads useful for the development of photonic applications due to their synthetic accessibility and tunable photonic properties. In this communication, a preliminary study on the influence of the structure of both the BODIPY chromophore and the bi(polyarene) moiety over the chiroptical properties of this family of O-BODIPYs is carried out, directed to the improvement of said properties for their use in chiroptic applications.
