Ullazine-based materials: towards novel opportunities in organic electronics

Abstract

Polycyclic aromatic hydrocarbons (PAHs) constitute a remarkable class of organic compounds that exhibit a large palette of electronic and optical properties. During the last decade, particular interest has been devoted to these PAHs driven by their successful application in organic electronics. Controlled heteroatom-doping of PAHs (Het-PAHs) offers additional possibilities for property modulation, rendering these derivatives very appealing for the development of high performing materials. In this article, we report a newly emerging class of materials based on a N-PAH class known as ullazine. Briefly covering different synthetic methodologies, their properties will be highlighted with special attention to their current fields of application, mostly in solar energy conversion, although there is great promise for this type of Het-PAH-based material.
