Cover Feature: Synthesis and Photophysical Studies of Dibenzophosphole Oxides with D–A–D Triad Structures (Eur. J. Org. Chem. 23/2019)

The Cover Feature shows dibenzo‐phosphole oxide (DBPO) lamps covered by diarylamine or carbazole moieties. DBPO is one of popular core units to create derivatives that have interesting electronic and optical properties. DBPO analogs containing electron‐donating units at 2‐ and 8‐positions are important, because they are donor–acceptor–donor (D–A–D) type substances which typically display intramolecular charge transfer emission. Unfortunately, studies of these substances are limited. We synthesized these analogs and investigated structures, light emission, and electrochemical properties.
