    © 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim A soluble directly 2,2′-linked tetracene dimer was synthesized. Dimerization of 8-bromo-2,3-dihexyl-5,12-tetracenequinone afforded the corresponding bitetracenequinone, which was converted into a tetracene dimer by sequential addition of 1-hexynyllithium and SnCl 2 /HCl. The synthesized tetracene dimer with four hexyl and four 1-hexynyl groups was highly soluble in CH 2 Cl 2 and THF, and the solutions were unstable under air and room light. The compound was studied by X-ray single crystal analysis, UV/Vis, and fluorescence spectroscopy, cyclic voltammetry, and density functional theory (DFT) calculations. In the crystal, two tetracene rings take a coplanar conformation although DFT calculations demonstrated that such a molecular structure is energetically unfavorable. The tetracene dimer had red-shifted absorption maxima and large molar extinction coefficients compared with the corresponding tetracene monomer. The tetracene dimer also showed amphoteric redox properties and p-type semiconducting behavior.

    © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim In this study, mechanochromic luminescence was induced in a complex of mechano-inactive compounds. Dye/acid complexes containing the same π-conjugated backbones were prepared. While the luminophore showed blue and red shifts in photoluminescence spectra when combined with different acids by grinding, it exhibited slight mechanoresponsiveness itself. Also, compounds with similar molecular backbones to the dye/acid complex were synthesized to clarify the color change mechanism. The compounds showed both blue and red shifts in photoluminescence and diffuse reflectance spectra upon grinding, indicating that mechanochromic luminescence in the hydrogen-bonded complex is like its monomeric analogue and that aggregation structure plays an important role in mechanoresponsive behavior rather than the π-conjugated structure. It was shown that a color change can be mechanically induced by imitating the solid-state aggregation structure of other mechanoresponsive compounds without synthetic modification.

  • Synthesis and properties of π-extended fluoranthene derivatives from 1,2-diarylacenaphthylene derivatives

    © 2018 Elsevier Ltd Acenaphthylene units work as a useful platform for the synthesis of polycyclic aromatic hydrocarbons (PAH). Three 1,2-diarylacenaphthylene derivatives (9-phenanthryl, 7-t-butyl-2-pyrenyl and 2-naphthyl) were prepared by Suzuki-Miyaura coupling of 1,2-dibromoacenaphthylene with the corresponding boronic acids and ester. The Scholl reaction of the phenanthryl derivative affords a donor-acceptor type fluoranthene derivative possessing a hemi-coronene structure by forming two C–C bonds between phenanthryl groups. The reaction of the pyrenyl derivative allows one C–C bond formation to give a helicene-type fluoranthene derivative. The reaction of the naphthyl derivative provides an asymmetric fluroranthene derivative having an anthracene unit accompanied with one C–C bonding reaction, while a photochemical cyclization followed by dehydroaromatization reaction of the compound gives a symmetric fluoranthene derivative with a [5]helicene structure.
