Organic Light‐Emitting Diodes from Symmetrical and Unsymmetrical π‐Extended Tetraoxa[8]circulenes

Abstract

Acid-mediated condensation of a 2,3-dialkyl-1,4-benzoquinone with 1,4-naphthoquinone produces a series of alkane-soluble π-extended tetraoxa[8]circulenes; these structures (shown here) were successfully incorporated in organic light-emitting diodes.
