Abstract

Abstract : In article number1805058, Frank Würthner and co‐workers report on the controlled supramolecular packing of highly dipolar merocyanine dyes to fabricate ultra‐narrowband photodiodes. By strategic design of the substituents' sterics, the nine investigated merocyanine dyes afford distinct different optical signatures in the solid state, giving rise to either H‐ or J‐aggregate properties with ultra‐narrow bandwidths. Such thin films are applied to yield transparent organic photodiodes in the interesting blue (H) and NIR (J) spectral range.
