4,7-Bis(dimethylamino)benzimidazoles and twin-type derivatives: reversible two-stage redox system modulated by proton-transfer

Autor: Kimio Akiyama, Yoshiaki Obana, Kenshu Fujiwara, Tsutomu Miyashi, Takanori Suzuki, Takanori Fukushima, Hidetoshi Kawai, Mayu Saito, Yoshiaki Tsubata

Publikováno v: Tetrahedron Letters. 44:7881-7884

The title electron donors 1 as well as their conjugate bases 2− undergo reversible two-stage one-electron oxidation. ESR analysis indicated the important contribution of zwitterionic structure for radicals 2 . Bis(zwitterionic) but not quinoid stru

Development of Novel Blue Light-emitting Polymers for PLED

Autor: Chizu Sekine, Toshihiro Ohnishi, Shuji Doi, Masato Ueda, Yoshiaki Tsubata, Takanobu Noguchi

Publikováno v: Journal of Photopolymer Science and Technology. 16:303-308

Various kinds of conjugated polymers of arylene vinylene and arylene units have successfully been synthesized. They are suitable for light-emitting materials of PLED. Although some of them showed blue emission, they are not sufficient for practical d

Single-component organic semiconductors based on novel radicals that exhibit electrochemical amphotericity: Preparation, crystal structures, and solid-state properties of N,N '-dicyanopyrazinonaphthoquinodiiminides substituted with an N-alkylpyridinium unit

Autor: Yoshiro Yamashita, Takayuki Ishida, Tsutomu Miyashi, Kenichi Imaeda, Takashi Nogami, Setsuko Miyanari, Takanori Suzuki, Yoshiaki Tsubata, Takanori Fukushima

Publikováno v: Journal of Organic Chemistry. 66(No. 1):216-224

N,N'-Dicyanonaphthoquinodiimines fused with a pyrazine ring 1 were prepared from the corresponding quinones 4. The new acceptors 1 have a planar pi-system and undergo reversible two-stage 1e-reduction. Quaternization of the pyridyl substituent in 1d-

Single-component organic conductors based on neutral radicals containing the pyrazino-TCNQ skeleton

Autor: Yoshiro Yamashita, Tsutomu Miyashi, Yoshiaki Tsubata, Takanori Suzuki

Publikováno v: The Journal of Organic Chemistry. 57:6749-6755

Pyrazino-TCNQ (1a) prepared from 5, 8-diiodoquinoxaline (4a) is, like TCNQ itself, a strong electron acceptor and gives a stable anion radical salt as well as highly conductive charge-transfer crystals with donors. Substituted derivatives 1b-i were s

Publikováno v: Chemistry Letters. 19:445-448

The title compounds, which were prepared from 2,3-diamino-1,4-naphthoquinone, are stronger acceptors than the related naphthoquinones. The studies of the cyclic voltammogram and MO calculation revealed that upon reduction electrons are first accepted

Novel blue light-emitting polymers for PLED

Autor: Masato Ueda, Shuji Doi, Takeshi Yamada, Yoshiaki Tsubata

Publikováno v: SPIE Proceedings.

We have been researching blue-emitting polymers and developed some novel polymers with blue fluorescence, which are not fluorene copolymers. Our previous works showed the dependence of EL efficiency on molecular weight of poly(p-phenylene vinylene) d
