  • Light-Induced Electron Spin Polarization in Vanadyl Octaethylporphyrin:  I. Characterization of the Excited Quartet State
    作者:Yuri E. Kandrashkin、Motoko S. Asano、Art van der Est

    corresponding values found from steady-state EPR spectra of the ground state. On the basis of these characteristics and numerical simulations, the polarization patterns are assigned to the excited quartet state. The values of the ZFS parameters of the trip-quartet obtained from simulation of the spectra (D = 17.5 mT and E = 1.5 mT) are comparable to those of the triplet state of the zinc and free base octaethyl
    给出了在各向同性和部分有序冷冻溶液中基八乙基卟啉的激光闪光自旋极化瞬态电子顺磁共振(TREPR)光谱,并将其与相应的发光数据进行了比较。TREPR光谱显示出与核的良好分辨的超精细耦合以及具有零场分裂(ZFS)典型特征的多重极化图。从光谱评估的超细耦合张量的主值是从基态的稳态EPR光谱中找到的相应值的1/3。基于这些特征和数值模拟,将偏振图案分配给激发四重态。通过光谱模拟获得的三重奏四重奏的ZFS参数值(D = 17.5 mT和E = 1。5 mT)相当于和游离碱八乙基卟啉的三重态。发现自旋偏振的寿命与温度有关,并且与光发射的寿命基本相同。使用一个模型可以合理化温度依赖性,在该模型中,三重奏四重奏和双重奏都发生基态衰减,即使在15 K时,它们也处于热平衡状态。该模型与观察到的自旋极化寿命相吻合三重奏四重奏和双重奏之间的能隙为47 cm(-1)。结果表明,自旋偏振在激光闪光后从早期的多
  • Insensitivity of Vanadyl−Oxygen Bond Strengths to Radical Type (<sup>2</sup>A<sub>1u</sub> vs <sup>2</sup>A<sub>2u</sub>) in Vanadyl Porphyrin Cation Radicals
    作者:Kazimierz Czarnecki、Leonard M. Proniewicz、Hiroshi Fujii、David Ji、Roman S. Czernuszewicz、James R. Kincaid
    DOI:10.1021/ic981369g
    日期:1999.4.1
    Resonance Raman (RR) spectra are reported for vanadyl octaethylporphyrin, OV(OEP), tetramesityltetramethylporphyrin, OV(TMTMP), and tetramesitylporphyrin, OV(TMP), and their corresponding pi-cation radicals obtained by chemical and electrochemical oxidation. The behavior of the nu(2) RR porphyrin "marker band", which moves to higher frequency upon oxidation of the OV(OEP) and OV(TMTMP) and to lower frequency for OV(TMP), shows that the resultant cation radicals have predominantly (2)A(1u) and (2)A(2u) ground states, respectively. In contrast to earlier work (Macor, K. A.; Czernuszewicz, R. S.; Spiro, T. G. Inorg. Chem. 1990, 29, 1996), it is demonstrated here that the shift of the nu(V=O) is insensitive to radical type, behavior which is in agreement with similar studies of the ferryl analogues (Czarnecki, K.; et al. J. Am. Chem. Soc. 1996, 116, 2929 and 4680). It is suggested that the observed downshifts of the nu(V=O) previously reported for RR spectra of vanadyl porphyrin pi-cation radicals, relative to their neutral parents, are most reasonably ascribed to trans oxo ligand coordination (most probably a water molecule) during low-temperature electrochemical oxidation of the neutral species.
