, p. 1073 - 1079 (2014/01/06)
A convenient and regioselective synthesis of porphyrin diarylthiazoles is reported via the reactions of alkynyl(aryl)iodonium tosylates and porphyrin thioamides. Among the synthesized porphyrin diarylthiazoles, compounds 6d and 6f have shown significant i

experimental part, p. 7434 - 7444 (2011/09/14)
Efficient electronic energy transfer (EET) in the newly synthesized dyads comprised of zinc porphyrin covalently linked to one, two or four numbers of boron dipyrrin (BDP) entities is investigated. Both steady-state and time-resolved emission as well as t
Synthesis of a beta-turn forming depsipeptide for hydrogen bond mediated electron transfer studies
Williamson, David A.,Bowler, Bruce E.
, p. 12357 - 12372 (2007/10/03)
Hydrogen bonds are believed to play an important role in the mediation of electron transfer processes in proteins. A porphyrin/depsipeptide/p-benzoquinone molecule has been synthesized to help understand this role of hydrogen bond mediated electron transfer in proteins. The synthesis, room temperature folding conformation, and steady-state electron transfer are described.

Zinc hybrid porphyrin dimer(ZnTTP-C2-H2PFPP, ZnTTP-C2-H2TTP, ZnPFPP-C2-H2PFPP, and ZnPFPP-C2-H2TTP) and manganese (III) halogenated porphyrin dimers (MnPFPP-C2-MnPFPP MnPFPP-C2MnDCPP, and MnDCPP-C2-MnDCPP) covalently bridged by an ethylene moiety (Scheme
Energy transfer in β-turned peptide-bridged porphyrin dimers
Tamiaki,Nomura,Maruyama
, p. 3062 - 3068 (2007/10/02)
β-Turned peptide-bridged diporphyrinyl compounds were prepared. Each isomeric monozinc complexes were easily available; metal-free porphyrin-peptide-zinc porphyrin and zinc porphyrin-peptide-metal-free porphyrin. In the isomers, the intramolecular energy transfer efficiencies from zinc porphyrin moiety to metal-free porphyrin moiety were the same from analysis of the steady-state fluorescence spectra, indicating that the efficiencies should be independent upon the linked peptide spacer and dependent upon the distance between the porphyrin moieties in the molecule. Singlet energy might migrate intramolecularly from zinc porphyrin moiety to metal-free one mainly by through-space mechanism.

The synthesis of the linked porphyrin-cyclodextrin 3 and its zinc complex 4 is described and their characterization by 1H nmr, 13C nmr, circular dichroism, ultraviolet, and infrared spectroscopy is reported.The linked porphyrin-cylod
Syntheses of Covalently-Linked Porphyrin-Quinone Complexes (1)
Kong, Josephine L. Y.,Loach, Paul A.
, p. 737 - 744 (2007/10/02)
A synthetic route for the preparation of covalently-linked porphyrin-quinone and metalloporphyrin-quinone complexes as models for the phototrap in bacterial photosynthesis is described. 5-(4-Carboxyphenyl)-10,15,20-tritolylporphyrin, prepared by a mixed aldehyde approach, was attached to a benzoquinone center with a propanediol bridge by means of ester linkages.The starting point for the benzoquinone moiety was 2,5-dihydroxyphenylacetic acid, whose hydroquinone function was first protected by preparing its dimethylether.The spacing between the two centers of the complex could be altered simply by varying the length of the bridging group (a diol) employed.Boron tribromide was used to unmask the quinol derivatives in the final coupled products.The zinc(II) derivative of porphyrin quinone comple was prepared ba addition of a saturated solution of zinc acetate in methanol to a solution of the corresponding porphyrin-hydroquinone complex in dichloromethane at room temperature.The structures of these complexes were confirmed by nmr spectroscopy, uv-visible absorption, and mass spectroscopy.Oxidation of the quinol moiety in the covalently-linked complex to its corresponding quinonoid derivative was accomplished by treating a solution of the complex in dichloromethane with a stoichiometric amount of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone, a high potential benzoquinone.
