We report the synthesis of processible (dihydro)pyracyclene‐ and acenaphthylene‐substituted azaacenes using condensation reactions in solution. The targets are characterized via cyclic voltammetry, X‐ray crystallography, UV/Vis, fluorescence spectroscopy and DFT/NICS calculations. Formal hydrogenation of the annulated five‐membered ring surprisingly alters emission in the solid‐state as a consequence

An organic compound, a three-dimensional organic structure formed by using the organic compound, a separation sieve and an optical layer having the organic structure, and an optical device having the optical layer as an optical amplification layer are provided. The organic structure includes a plurality of organic molecules self-assembled by non-covalent bonding. Each of the unit organic molecules has an aromatic ring, a first pair of substituents being connected to immediately adjacent positions of substitutable positions of the aromatic ring, and a second pair of substituents being connected to immediately adjacent positions of remaining substitutable positions of the aromatic ring. The unit organic molecules are self-assembled by van der Waals interaction, London dispersion interaction or hydrogen bonding between the first and the second pairs of the substituents and by pi-pi interactions between the aromatic rings.

1,2-Diarylethanes and 1,2-diarylethylenes can be oxidized directly to 1,2-diaryldiketones in good yields by reaction with benzeneseleninic anyhdride (BSA) at 120 °C in chlorobenzene.

Direct evidence for the existence of an intermediate bisketene (Φ=0.14, e575=2300 M−1 cm−1), generated from pyracyloquinone, was obtained by laserflashphotolysis with UV/VIS and IR detection. The bisketene was found to react with DMSO to give acenaphthylene-5,6-dicarboxylic anhydride and dimethyl sulfide, quantitatively.
