  二苯并富烯和9-甲基蒽酮的自由基加合物-一项ESR研究

  摘要：

  使标题化合物与一系列R 3 M.基团（M = C，Si，Ge，Sn，P，O，S）反应，得到相应的顺磁性加合物。在9-亚甲基蒽酮基团的情况下，即使在IV B族有机金属基团上，环碳-碳双键选择性地发生加成，其对羰基氧的攻击将产生热力学上更稳定的加合物。辐射9-甲基蒽酮溶液时，发生了光致自反应，导致形成了二聚体。根据测得的ESR光谱参数，讨论了加合物的结构，以及R n M基团对β-质子超细分裂常数的影响。

  Magnetic Field Effects on the Photodissociation Reaction of Triarylphosphine in Nonviscous Homogeneous Solutions

  摘要：

  The magnetic field effects (MFEs) on the photodecomposition reactions of triphenylphosphine and its halogen and methyl derivatives are investigated in fluid solutions. The yield of diarylphosphinyl radicals decreased with increasing magnetic field from 0.1 to 5 T but was stationary below 0.1 T and above 5 T. The MFE becomes larger by the substitution of halogen atoms and the 3- or 4-methyl group. In cyclohexane, the yields of the escaped diaryl phosphinyl radicals at 1 T are reduced to 0.69, 0.55, 0.59, and 0.56 of those at 0 T for triphenylphosphine and its tris(4-chloro), tris(3-methyl), and tris(4-methyl) derivatives, respectively. This magnetic field dependence was ascribed to originate from the deactivation process of the excited triplet state, which is a variant of the d-type triplet mechanism originally proposed by Steiner. The interaction between the closely lying npi* and pipi* states makes their solvent dependence complicated.

  Fluorescence, phosphorescence, and excitation spectra were measured on the title compound. These results were augmented with polarization ratios obtained at 77 K and detailed studies of the temperature dependence of the phosphorescence in the 77-4 K range. The phosphorescence decay rate at 4 K was also recorded as a function of an applied magnetic field. Ah the results are consistent with a 4d(2)Rh(1) --> 6p(z)Au(1) orbital promotion leading to emitting (1)A(1), (3)A(1) terms in pseudo-C-2v symmetry. The (3)A(1) term is split by spin-orbit coupling into a forbidden A(2) state lying lowest followed by a quasi-degenerate pair, [B-i(x), B-2(y)] lying similar to 16 cm(-1) higher that decays >500 times faster than the lowest one.
