Anomalous 13C NMR Chemical Shifts of High-spin Saddle Shaped Manganese(III) Octaethyltetraphenylporphyrin Complexes

Akira Ikezaki、Mikio Nakamura、Ru-Jen Cheng2005-12-27Chemistry Letters

Abstract NMR spectra of highly saddled Mn(III) porphyrinates such as Mn(OETPP)(CD3OD)2+ have been measured. The extraordinarily upfield shifted meso-13C signals, which reach as much as −492 ppm at 298 K, are ascribed to the dx2−y2–a2u, dxy–a1u, and dπ–3eg interactions, the former two of which occur only when the porph…

Influence of Electronic Properties of Naphthalene Compounds on Contact Angles

Hossein Tavana、Michael L. Hair、A. W. Neumann2005-12-27The Journal of Physical Chemistry B

Contact angles of a homologous series of naphthalene compounds on films of a fluorinated acrylate polymer (EGC-1700) deviate from an ideal pattern of contact angles. The deviations increase with the electronegativity of the constituent atoms of the liquid molecules. The results suggest that an uneven distribution of e…

Abstract We have studied the effect of cryomilling (high‐energy ball milling under cryogenic temperature) on the thermal behaviors of poly(ethylene terephthalate) (PET) by comparing with original PET and quenched PET. Cryomilling induced the amorphization of crystalline PET, but the thermal behaviors of amorphous PET…
