Low-coordinated organophosphorus compounds featuring P=C units have been studied in recent years due to their unique optoelectronic properties. Benzoxaphospholes (BOPs) are a class of heterocycles which a benzene ring fused to a phosphorus and oxygen containing five membered ring. These materials show remarkable luminescent properties. In order to improve their air-stability, bulky groups are introduced into the heterocyclic ring. The air-stability and photophysical properties of the new materials are characterized.
