    The synthesis of dodecasubstituted porphycenes has not been reported, to date. Herein, the preparation of tetramethyloctaethylporphycene by a McMurry-type coupling of 3,3′,4,4′-tetraethyl-5,5′-diformyl-2,2′-bipyrrole was ...
  • Kuzuhara, Daiki; Yamada, Hiroko; Xue, ZhaoLi; Okujima, Tetsuo; Mori, Shigeki; Shen, Zhen; Uno, Hidemitsu (The Royal Society of Chemistry, 2010-11-16)
    The metal-free and meso-free [14]triphyrin(2.1.1) compound was successfully prepared based on the intramolecular McMurry coupling reaction of diformyl-tripyrrane in 16% yield, and was converted to the bowl-shaped ...
  • Kuzuhara, Daiki; Xue, ZhaoLi; Mori, Shigeki; Okujima, Tetsuo; Uno, Hidemitsu; Aratani, Naoki; Yamada, Hiroko (The Royal Society of Chemistry, 2013-08-21)
    Boron complexes of [14]triphyrins(2.1.1) were prepared from free-base [14]triphyrins(2.1.1) with phenylboron dichloride. The absorption spectrum of the meso-free [small beta]-alkyl-triphyrin boron complex in CH2Cl2 showed ...

    Novel bisimide-fused acenes were synthesized viabismuth triflate mediated double-cyclization reaction of acid chlorides and isocyanates. Their optical and electrical properties revealed significantly smaller HOMO-LUMO gaps ...
  • Aotake, Tatsuya; Ikeda, Shinya; Kuzuhara, Daiki; Mori, Shigeki; Okujima, Tetsuo; Uno, Hidemitsu; Yamada, Hiroko (WILEY-VCH Verlag, 2012-02-08)
    5,14-α-Diketopentacene, a structural isomer of 6,13-α-diketopentacene, was prepared from pentacene in three steps. In addition to the typical n-π* absorption of the diketone moiety at around 468 nm and the anthracene-like ...
  • Kuzuhara, Daiki; Yamada, Hiroko; Mori, Shigeki; Okujima, Tetsuo; Uno, Hidemitsu (World Scientific Publishing, 2011-09-01)
    A series of benzoporphycenes and naphthoporphycenes and their zinc complexes were prepared from bicyclo[2.2.2]octadiene fused porphycenes by a retro-Diels-Alder reaction and their photophysical properties were studied. ...
