European Journal of Organic Chemistry 頁： 1341 - 1349 2008年3月

記述言語：英語掲載種別：研究論文（学術雑誌）

Acid-catalyzed condensation of meso-pentafluorophenyl di- pyrromethane and pentafluorobenzaldehyde at 0 degrees gave a series of expanded porphyrins with even number of pyrrolic subunits up to octadecaphyrin(1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1) in improved yields, particularly for larger expanded porphyrins. The solid-state structure of decaphyrin(1.1.1.1.1.1.1.1.1.1) was revealed by X-ray diffraction analysis to be a crescent-like conformation. The Soret-like absorption bands are increasingly redshifted as the size of the ring increases, but such a trend becomes nearly saturated for hexadecaphyrins (1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1) which exhibit bands in the near-infrared region at 939 and 953 nm, respectively.

Möbius aromaticity in N-fused [24]pentaphyrin upon Rh(I) metalation 査読有り

Jong Kang Park, Zin Seok Yoon, Min-Chul Yoon, Kil Suk Kim, Shegeki Mori, Ji-Young Shin, Atsuhiro Osuka, Dongho Kim

Journal of the American Chemical Society 130 巻 ( 6 ) 頁： 1824 - 1825 2008年2月

記述言語：英語掲載種別：研究論文（学術雑誌）

NFP5s are interesting platfroms to realize Huckel aromaticity, Huckel antiaromaticity, and Moebius aromaticity depending on the number of pai-electrons, meso-substituent, and metalation. Rh-[24]NFP5 has been comfirmed as a Moebius aromatic molecule by the crystal structure, 1H NMR spectrum, NICS calculation, and TPA cross-section values. This molecule is the smallest Moebius aromatic system with distinct diatropic ring current.

New two metal complexes, di-(Phenyl dipyrrylmethene)zinc (Zn(PPM)2) and di-(Pentafluorophenyl dipyrrylmethene)zinc (Zn(PFPPM)2) as a host material instead of Alq3 were synthesized. To evaluate electroluminescent properties, multi- layered organic light-emitting devices were fabricated by using 4-(dicyanomethy- lene)-2-tert-buthyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) as a dopant and Alq3 as an electron transporting layer. Alq3 and Zn(PPM)2 host EL devices exhibited DCJTB emission peak at around 617 nm due to energy transfer from Alq3 and Zn(PPM)2 to DCJTB. However Zn(PFPPM)2 host device shows no DCJTB emission peak because Zn(PFPPM)2 device emit EL light of 563 and 700 nm. The Zn(PPM)2 device showed same luminance efficiency as Alq3 device, but showed better power efficiency of 1.2 times than Alq3 device.

N-fused Pentaphyrins and Their Rhodium Complexes: Oxidation-Induced Rhodium Rearrangement 査読有り

Shigeki Mori, Ji-Young Shin, Soji Shimizu, Fumiaki Ishikawa, Hiroyuki Furuta, Atsuhiro Osuka

Chemistry-A European Journal 11 巻 ( 8 ) 頁： 2417 - 2425 2005年4月

記述言語：英語掲載種別：研究論文（学術雑誌）

meso-Aryl-substituted pentaphyrins were isolated in the modified Rothemund-Lindsey porphyrin synthesis and a [22]NFP5 and [24]NFP5, which were reversibly interconvertible by means of two electron reduction with NaBH4 or two-electron oxidation with DDQ. Judging from 1H NMR data, [22]NFP5 is aromatic and possesses a diatropic ring current, while [24]NFP5 exhibits partial antiaromatic character. Metalation of [22]NFP5 with rhodium(I) salt led to isolation of rhodium complexes, whose structures were unambiguously characterized by X-ray diffraction analyses and were assigned as conjugated 24- and 22-pai electronic systems, respectively. Upon the treatment with DDQ, those are interconvertible with an unprecedented rearrangement of the rhodium atom.

Protonated Dipyrromethenes and Tetrahalozinc Anions as Synthons in the Solid State 査読有り

担当区分：筆頭著者記述言語：英語掲載種別：研究論文（学術雑誌）

(HL)2ZnBr4 and (HL)2ZnCl4 were prepared by the addition of HBr and Hcl into a acetonitrile solution of Zn(II)L2, and their structures were determined by X-ray diffraction analysis. The X-ray crystallographic data show super structures that have hydrogen bonds between the terahalozinc anions and the protonated dipyrromethene cations.

A ring-contracted sister of porphyrin, norcorrole, has been synthesized efficiently as a stable molecule by a nickel-templated strategy. The norcorrole complex is stable but exhibits a distinct antiaromatic character according to the Hückel rule. Oxidation of the norcorrole complex provides an aromatic oxacorrole complex.
