  模板辅助配体封装；异常配位几何对超分子吡啶基膦-Zn（II）卟啉组装体的影响

  摘要：

  三（对吡啶基）膦模板（1）已与一系列内消旋取代的Zn（II）-四苯基卟啉配合物（2-10）结合使用，可通过Zn-N（pyr）相互作用产生超分子包封的配体组装体。超分子配体1. [2]（3）的结构特征已使用X射线晶体学，NMR光谱和UV-vis光谱进行了详细研究。在溶液（1：3）中测定的吡啶基膦-卟啉化学计量与在固态下观察到的（2：5，对于组装[1]（2）。[2]（5））有显着差异。差异源自一个Zn中心之一的异常配位行为，该中心被八面体通过两个不同的1分子的吡啶基的双轴向配位包围。

  UV-Vis, Fluorescence, and EPR Studies of Porphyrins in Bilayers of Dioctadecyldimethylammonium Surfactants

  摘要：

  The incorporation characteristics of three simple tetraarylporphyrins into bilayers of dioctadecyldimethylammonium surfactants was studied by UV-vis, fluorescence, and EPR spectroscopy. The porphyrins used are tetraphenylporphyrin (TPP), tetrakis(4-(hexadecyloxy)phenyl)porphyrin (THPP), and tris(4-(hexadecyloxy)phenyl)(4-methylpyridinium) porphyrin tosylate (TrHPyP). At low porphyrin to surfactant molar ratios (<5 x 10(-4)) the porphyrins show a strong fluorescence. Increasing this ratio to 5 x 10(-3) causes a change in the UV-vis spectra and a decrease of the fluorescence intensity. Time-resolved fluorescence measurements indicated that the latter is due to the formation of non-fluorescent porphyrin aggregates. The spectral characteristics of the porphyrin aggregates are discussed in terms of the formation of different types of aggregates. The location of the porphyrins within the bilayers was investigated by fluorescence quenching experiments using iodide, 9(10)-bromooctadecanoic acid, and 16-bromohexadecanoic acid. These experiments suggest that THPP is located in the middle of the bilayer and TrHPyP near the aqueous interface. For the parent compound TPP no well-defined position was found. EPR spectroscopy on cast films of dioctadecyldimethylammonium surfactants with the copper derivatives of the porphyrins incorporated (porphyrin-to-surfactant ratio = 5 x 10(-3)) revealed a clear anisptropic distribution of the latter molecules in the cast bilayers. The angles between the porphyrin normals and the bilayer normal were determined by comparison of experiment with simulated spectra. In the case of THPP and TrHPyP these angles agree very well with an arrangement in which the long porphyrin axis lies parallel to the bilayer surface. The arrangement of TPP aggregates could not be established.
