Abstract
In this account, we describe our efforts in developing the chemistry of the highly luminescent dithieno[3,2-b :2′,3′-d ]phosphole system over the last ten years. We provide an overview of the synthetic possibilities and the inherent tunability of the emission properties offered by this particular heterole.
