Intramolecular photoinduced electron-transfer processes in buta-1,3-diynyl-benzene-linked porphyrin-fullerene dyad Ken-ichi Yamanaka*, Mamoru Fujitsuka, Yasuyuki Araki, Kentaro Tashiro, Azumi Sato, Tetsuro Yuzawa and Takuzo Aida DOI: 10.1142/S108842460700045X Page: 397-405 Intramolecular electron-transfer process of porphyrin-fullerene dyad linked by phenyl buta-1,3-diynyl-phenyl unit (ZnP-sp-C60) was studied by laser flash photolysis. The lifetime of the radical-ion pair of ZnP-sp-C60 was longer than those of directly connected dyads with buta-1,3-diynyl bridge and buta-1,3-diynyl-phenyl bridge by insertion extra phenyl group in addition to the pyrrodino ring.
Syntheses and properties of acetylene-linked bis- and trisporphyrins toward two-photon photodynamic therapy Yusuke Inaba, Kazuya Ogawa* and Yoshiaki Kobuke* DOI: 10.1142/S1088424607000461 Page: 406-417 Acetylene-bridged bisporphyrins and trisporphyrins having bulky branch-type bis(carboxylethyl)methyl meso-substituents were synthesized. The effective two-photon absorption cross section values at 890 nm were measured by using a nanosecond Z-scan method. The singlet oxygen generation in water was confirmed.
Noncovalent porphyrin-functionalized single-walled carbon nanotubes: solubilization and spectral behaviors Hiroto Murakami, Genki Nakamura, Takuro Nomura, Takeshi Miyamoto and Naotoshi Nakashima* DOI: 10.1142/S1088424607000473 Page: 418-427 We describe the solubilization/dispersion of the as-produced and purified single-walled carbon nanotubes (raw-SWNTs and p-SWNTs) with protoporphyrin IX derivatives and tetraphenylporphyrin iron(III) chloride, the spectral behavior of the octaalkylporphyrins-solublilized shortened-SWNTs (s-SWNTs), and the electrochemistry of a p-SWNTs/FePP cast film on a glassy carbon (GC) electrode.
Pyrene-to-porphyrin excited singlet energy transfer in LBL-deposited LDH nanosheets Tatsuto Yui, Tatsuya Kameyama, Takayosi Sasaki, Tsukasa Torimoto* and Katsuhiko Takagi* DOI: 10.1142/S1088424607000485 Page: 428-433 Nano-ordered hybrid films of layered double hydroxide (LDH) nanosheets and two types of anionic dye molecules, i.e. tetrakis(4-carboxyphenyl)porphyrin (TCPP) and 1,3,6,8-pyrenetetrasulfonic acid (PTSA), were prepared by a layer-by-layer deposition (LBL) method. Photo-induced energy transfers (PET) between the PTSA and TCPP in the LBL-deposited hybrid layers were investigated.
Synthetic hydroxymethyl-porphyrins for protection of carboxy group Hitoshi Tamiaki*, Kouji Kumon and Reiko Shibata DOI: 10.1142/S1088424607000497 Page: 434-441 Synthetic hydroxymethyl-porphyrins were useful for protection of carboxy groups. The protective groups were successfully applied to liquid phase peptide syntheses.
Single-wall carbon nanotube porphyrin nanoconjugates Christian Ehli, Stéphane Campidelli, Fulvio G. Brunetti, Maurizio Prato* and Dirk M. Guldi* DOI: 10.1142/S1088424607000503 Page: 442-447 In this manuscript, we are describing the synthesis, microscopic and spectroscopic characterization of a novel donor-acceptor prototype, namely, a single wall carbon nanotube (SWNT) nanoconjugate bearing a covalently linked free base porphyrin (H2P). In the described SWNT-H2P nanoconjugate the electronic features of SWNT are largely retained, when compared to pristine SWNT. Supplementary Material
Synthesis and photophysical properties of water-soluble dendrimers bearing a phthalocyanine core Masakazu Nishida, Atsuya Momotake, Yoshihiro Shinohara, Yoshinobu Nishimura and Tatsuo Arai* DOI: 10.1142/S1088424607000515 Page: 448-454 We prepared the first- and second-generation dendrimers (WG1-PC and WG2-PC) having water-soluble substituents as a peripheral group to investigate aggregation behavior in an aqueous solution. The introduction of the second-generation dendrons to a phthalocyanine core can prevent from forming aggregation leading to avoid self-aggregation and undesirable deactivation process.
Charge separation in a conformationally-flexible porphyrin-fullerene dyad synthesised using cross-metathesis Toby D.M. Bell, Kenneth P. Ghiggino*, Andrew Haynes, Steven J. Langford and Clint P. Woodward DOI: 10.1142/S1088424607000527 Page: 455-462 A cross metathesis strategy is used to synthesize a flexibly-linked porphyrin-fullerene dyad. Photoinduced electron transfer leads to a charge-separated state with a lifetime of 330 ns in tetrahydrofuran solvent. Supplementary Material
Synthesis and photophysical and electrochemical properties of a binuclear Ru(bpy)3-Cu(III) corrole complex Yan Gao, Jianhui Liu*, Wenfeng Jiang, Ming Xia, Wei Zhang, Minna Li, Björn Åkermark and Licheng Sun* DOI: 10.1142/S1088424607000539 Page: 463-469 A novel binuclear Ru-Cu complex, composed of a copper(III)-corrole and a ruthenium(II) tris(bipyridine) moiety linked by an amide bond, has been obtained. Compared to the parent [Ru(bpy)3]2+, the emission of the desired complex was substantially quenched when the MLCT of [Ru(bpy)3]2+ was selectively photoexcited.
