Abstract
In article number 1805058, 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.
