Abstract

Bis(dioxaborole)s result from the condensation reaction connecting a diboronic acid with an aromatic 1,2-diol such as catechol (Scheme 1). In these materials the empty p-orbitals on the boron atoms and the lone pairs of electrons on the oxygen atoms are in conjugation with the phenyl rings generating an extended π-conjugated system. 1 The planarity between linked aromatic rings plays a great role in defining the optical and electronic properties of this type of ...
