Publikováno v: Thermochimica Acta. 240:109-115
The thermal behavior of Co(TPP)(L), Co(Tp-CH 3 PP)(L), and Co(Tp-OCH 3 PP)(L) was investigated in the solid state, where TPP, Tp-CH 3 PP, and Tp-OCH 3 PP represent tetraphenylporphyrin, tetra( p -methylphenyl)porphyrin, and tetra( p -methoxyphenyl)po

Recognition of axial ligands by a zinc porphyrin host on the basis of nonpolar interligand interaction
Autor: Eishin Kyuno, Hiroyasu Imai, Shigeo Nakagawa
Publikováno v: Journal of the American Chemical Society. 114:6719-6723
A porphyrin host with a preorganized cavity on each face has been synthesized and characterized. The constants for association of the zinc complex of the porphyrin with various amine ligands were determined and compared with those of [meso-tetrakis(p

Modified picket fence porphyrin Fe(III) and Zn(II) complexes as a model for hemoglobin mutants
Autor: Eishin Kyuno, Hiroyasu Imai, Shigeo Nakagawa
Publikováno v: Inorganica Chimica Acta. 193:105-109
Zinc(II) and iron(III) complexes of three modified picket fence porphyrins in which one of the four pivalamido pickets was replaced by a meta-methyl, -amino, or -hydroxy benzoylamino picket were synthesized. The iron complex containing the phenolic O

Resonance Raman spectroscopic detection of steric-induced distortions of axial ligand binding for dioxygen adducts of superstructured cobalt-porphyrin complexes
Autor: Yoshio Uemori, Eishin Kyuno, James R. Kincaid, Alan Bruha, Leonard M. Proniewicz, Kazuo Nakamoto
Publikováno v: Journal of the American Chemical Society. 113:9100-9104
Resonance Raman studies are carried out for the O2 adducts of superstructured "jellyfish" cobalt-porphyrin complexes with several trans-axial ligands, namely, pyridine, 3,5-lutidine, and imidazole as well as several of their deuteriated analogues. Tw

Proton NMR study of cobalt(II) and zinc(II) 'jellyfish' type porphyrins
Autor: Yoshio Uemori, Eishin Kyuno
Publikováno v: Inorganica Chimica Acta. 174:109-117
Proton NMR spectra for 'jellyfish' type porphyrinatocobalt(II) and zinc(II) complexes were measured. Upon complexing with cobalt(II), 1H NMR spectra of the porphyrin ligands suggest the deformations of the cavity structures, while such deformations w
