    On the Negligible Impact of Ruffling on the Electronic Spectra of Porphine, Tetramethylporphyrin, and Perfluoroalkylporphyrins
    摘要:
    In the first part of this paper, the syntheses, structural characterization, molecular modeling, and electronic spectra for planar and nonplanar perfluoroatkylated porphyrins, (R-f)(4)P's, are reported. These studies demonstrate that the intrinsic substituent effect of the perfluoroalkyl group on the long-wavelength electronic spectrum of porphyrins is substantial, and similar tin magnitude) to that of a phenyl ring, Moreover, it is shown that out-of-plane distortion of (R-f)(4)P'S has a negligible impact on their electronic spectra. These data bolster the findings of our earlier work and demonstrate that nonplanarity of (R-f)(4)P'S does not result in a red-shift in their optical spectra. In the second part of this paper, time-dependent density functional spectral calculations (B3LYP/6-311G*/TD) for porphine, 5,10,15,20-tetrakis(trifluoromethyl)porphrin and 5,10,15, 20-tetramethylporphyrin in a variety of ruffled conformations are reported. The results of these studies indicate that (1) substantial ruffling of porphyrins has a negligible effect upon their electronic spectra, (2) similarly small effects upon electronic spectra are predicted if electron-withdrawing or electron-releasing groups decorate the porphyrin periphery, (3) for sterically encumbered porphyrins, ruffling can actually result in hypsochromic shifts in various absorption bands, and (4) the bulk of the red-shift commonly thought to be due to nonplanar distortion actually arises from other substituent effects. These results pose serious challenges to previous theoretical and empirical studies that have sought to find a cause-and-effect relationship between nonplanarity and electronic spectra in porphyrins.

    简要概述 英文 法文 基于吡咯-亚醇衍生物,采用三种优化的实验条件合成了六种具有meso-多卤烷基链的双吡咯甲烷(DPM)。一方面,p-乙氧基苯铝醛与含有全氟烷基链(CF3、C3F7或C7F15)的DPM的缩合反应在氧化后以合理的产率生成了预期的trans-A2B2-卟啉。另一方面,从meso-(二氯甲基)双吡咯甲烷直接获得了5,15-二甲酰基-10,20-二芳基卟啉,而使用meso-(氯二氟甲基)双吡咯甲烷时则分离到了含有两个meso-酰氟基团的前所未见的卟啉的痕量产物。与以往报道的方法相比,双甲酰卟啉的直接形成具有竞争力,并已扩展到其他苯甲醛。通过结合光物理、 electrochemical、结构和理论研究,揭示了不同取代基对卟啉的电吸引特性。 补充材料: 本文的补充材料以单独文件形式提供: crchim-97-suppl.pdf

  • Energy-Gap Dependence of Photoinduced Charge Separation and Subsequent Charge Recombination in 1,4-Phenylene-Bridged Zinc-Free-Base Hybrid Porphyrins

    ZP(+)-HP- ion pairs have been estimated. Similar biphasic fluorescence decay has been observed for 5 ZH in benzene; this allows furhter estimation of the energy level of the ZP(+)-HP- ion pairs. The free-energy-gap dependence (energy-gap law) has been probed from the normal to the upper limit region for the rate of the charge separation alone, and only the inverted region for the rate of the charge

An ethyne porphyrin and an iodo porphyrin (either free base or zinc) are selectively joined via Pd(0)-catalyzed coupling reactions, affording a linear array with porphyrins in defined metalation states. Coupling of a zinc-porphyrin bearing iodo and ester groups with a free base porphyrin bearing ethyne and ester groups yielded the zinc-free base porphyrin dimer. Coupling

    New chemical compounds, bis(pyrrol-2-yl)halocarbylmethanes, also known as meso-halocarbyl dipyrromethanes, are made by recting pyrrole in either of two reaction schemes. Once such scheme converts pyrrole through an intermediate, a halocarbyl carbonyl pyrrole, to a [2-(1-hydroxyl-1-hydro-1-halocarbyl)pyrrole], and then converts the latter to the desired halocarbyldipyrromethane; the last step in this scheme is a novel and useful method in itself. The other such sequence converts pyrrole, by reaction with a halocarbyl aldehyde, directly to the desired halocarbyl dipyrromethane.

    控制单重态-三重态能隙 (Δ E ST ) 对于实现高效的能量转换反应、光化学反应轨迹和利用分子自旋物理学的新兴应用至关重要。尽管如此,尚未定义任何系统方法来调整 Δ E ST在简单的分子框架中,更不用说通过同时保持发色团大小和电子结构参数(例如 HOMO-LUMO 间隙)恒定的方法。结合分子设计、光物理和电位实验以及量子化学分析,我们表明激发单重态和三重态的电子-电子排斥程度可以通过简单的卟啉吸收剂的取代模式进行精细控制,从而能够调节通过电子-电子库仑 ( J ) 和交换 ( K ) 相互作用量级的设计限制,相对电子激发的单重态和三重态能量。这种方法调制 Δ E ST通过控制占据和虚拟分子轨道流形中的状态密度、自然跃迁轨道极化以及涉及选择的自然跃迁轨道对的一个电子跃迁的相对贡献来控制大小。该路线图调节占据和虚拟状态中的电子密度重叠,这些重叠定义了这些生色团的单重态和三重态波函数,使得尽管
