Abstract

Dibenzophospholes, phosphorus-containing π-conjugated cyclic compounds, have attracted considerable attention because of their potential applications in various functional materials such as those required for organic electroluminescent devices. Moreover, their synthetic methods have been widely developed. This review summarizes the construction strategies of dibenzophosphole scaffolds, including those developed recently.
