    生物金属卟啉氧化降解的可能中间体。八乙基甲酰胆绿素的镍、铜和钴配合物及其向 Verdoheme 的转化
    摘要:
    甲酰胆绿素和相关的叶绿素衍生分子是血红素分解代谢和其他生物学上重要的氧化过程的可能产物,并且可能最初以金属配合物的形式形成。为了探索与过渡金属离子结合的甲酰胆绿素部分的性质,已经制备了八乙基甲酰胆绿素 (H2OEFB) 与 Cu(II)、Ni(II) 和 Co(II) 的配合物,因为制备铁配合物的尝试仅产生不稳定的材料。通过 MgII(八乙基卟啉)与金属(II)乙酸盐光氧化制备的 MgII(OEFB)的金属转移产生低自旋配合物:CuII(OEFB)、NiII(OEFB)和 CoII(OEFB)。CuII(OEFB) 的单晶 X 射线衍射表明它由一个四配位铜 (II) 中心组成,该中心以扭曲的平面配位与四个氮原子结合。四吡咯配体具有螺旋几何形状。由于不对称单元中存在三个分子和C−H···O氢...

  • Alternant Bond Distances in Octaethylporphyrin π-Cation Radicals
    作者:W. Robert Scheidt、Beisong Cheng、K. Venugopal Reddy、Kristin E. Brancato

    日期:2017.4
    The possible appearance and nature of alternant bond distance patterns in the inner 16-membered ring of several octaethylporphyrin [Formula: see text]-cation radicals has been investigated. This study was made possible by recognizing an unexpected solvent system, namely dichloromethane/chloroform, even though the [Formula: see text]-cation species have extremely limited solubility in chloroform. A
    已经研究了几种八乙基卟啉[分子式:见正文]-阳离子自由基的内 16 元环中交替键距离模式的可能外观和性质。这项研究是通过认识到一种意想不到的溶剂系统(即二氯甲烷/氯仿)而成为可能的,尽管 [分子式:见正文]-阳离子物质在氯仿中的溶解度极为有限。通过单晶 X 射线结构测定研究了总共六种 [M(OEP[Formula: see text]][Formula: see text] 衍生物。两种新的生物在数量上显示出与先前观察到的相同的交替模式。新的络合物显示出较小但现在可能很重要的交替模式。然而,生物,经过两次独立分析,没有显示出交替模式的证据。两个不同的生物显示了环-环相互作用对前两个轨道能量的重要性。具有强烈重叠环的衍生物显示出交替的键距离模式,而另一个具有适度重叠的环对的衍生物则没有。这表明强环-环相互作用在导致伪 Jahn-Teller 状态中的重要性;这一假设也得到了其他先前结果的支持。

    Helical metal complexes of tetraphenylbilatrienones (TPBT) have been selectively synthesized, and for the first time, their structure was revealed by XRD. Contrary to theoretical predictions, their 20-phenyl group points alongside the tetrapyrrole backbone, yielding a well-defined molecule with stable helicity, 800 nm ECD absorption and – if copper is coordinated – noninnocent properties.

  • Q<i><sub>y</sub></i>-Excitation Resonance Raman Spectra of Chlorophyll <i>a</i> and Related Complexes. Normal Mode Characteristics of the Low-Frequency Vibrations
    作者:Chengli Zhou、James R. Diers、David F. Bocian
    DOI:10.1021/jp971965g
    日期:1997.11.1
    Q(y)-excitation resonance Raman (RR) spectra are reported for film aggregates of chlorophyll (Chi) a and a series of related complexes. The latter include Mg(II) octaethylporphyrin (MgOEP), Mg(II) trans-octaethylchlorin (MgOEC), methyl-9-desoxomesopyrochlorophyllide (DMPChl) a, and methylpyrochlorophyllide (MPChl) a. These complexes represent a series in which the structural complexities of Chl a (saturated pyrrole ring, isocyclic ring, C-9-keto group, C-2-vinyl group, and C-10-carbomethoxy group) are systematically added to the basic tetrapyrrole architecture. On the basis of comparison of the RR scattering characteristics of the different complexes and the predictions of semiempirical normal coordinate calculations, a self-consistent set of vibrational assignments has been developed for all the RR active modes in the low-frequency regime (100-1000 cm(-1)). The studies indicate that the low-frequency Vibrations encompass a diverse set of motions that include both the ring skeleton and peripheral substituent groups. However, modes in the very low-frequency regime (<250 cm(-1)) are primarily due to deformations of the substituent groups. Collectively, the normal mode characteristics of Chi a and the other Mg(II) complexes provide insights into the nature of the vibrational modes that are coupled to the photophysically important, lowest energy excited states of natural photosynthetic assemblies.
