The UV-vis and variable-temperature X-band EPR spectral studies (298-77 K) on p-cation of zinc(II) tetraphenylporphyrin (ZnTPP) have revealed for the first time a labile electronic ground state. The electronic structure changes from 2 A 2u to 2 A 1u as the temperature is lowered from 298 to 150 K. A
Zinc(II) complexes of substituted tetraphenylporphyrins, Zn[T(X-P)P], where X = H, p-F, p-Cl, m-Cl, p-CH 3 O, and m-CH 3 O, have been synthesized and characterized. Peripheral substitution shows marked changes in the chemical shifts of the phenyl proton resonances and E 1/2 values of the redox coupl
