Abstract:
Dibenzochalcogenophenes (DBC) have attracted huge attention ever since the discovery that they are able to act as potent (phosphorescent) emitters more than 60 years ago. From then on, they were extensively used as versatile emissive platforms for applications in materials science and optoelectronics. In this review, we focus on the main achievements of the past 20 years, highlighting especially monomolecular small purely organic compounds with less than 10 aromatic units and only one chalcogenophene moiety. Besides this, we wish to focus on their emission properties and to evaluate general design principles to fine-tune photophysical properties.
