  Self-Assembly of Porphyrin Arrays via Coordination to Transition Metal Bisphosphine Complexes and the Unique Spectral Properties of the Product Metallacyclic Ensembles

  摘要：

  Self-assembly of predesigned angular and linear dipyridylporphyrin modules with bisphosphine-coordinated Pd(II) and Pt(II) angular and linear modules leads to cyclic porphyrin arrays containing two or four units and ranging in size from 15 to 39 Angstrom. Multinuclear NMR spectra indicate high symmetry for these macrocycles. Restriction in rotation of trans-DPyDPP groups around the axis defined by the terminal metal-nitrogen bonds distorts the symmetry of the tetramers, but the rotation is unrestricted at elevated temperatures. Chiral metal triflates containing R(+)- or S(-)-BINAP phosphines promote formation of enantiomeric macrocycles with a puckered geometry CD spectra of the chiral macrocycles reveal a strong exciton coupling between the porphyrin chromophores in the tetramers. Emission spectra reveal moderate fluorescence quenching of the dipyridylporphyrin fluorophores upon treatment with metal triflates and concomitant incorporation into the macrocycles.

  Five bis-porphyrin copolymers have been obtained by an electropolymerization process using zinc β-octaethylporphyrin (ZnOEP) type macrocycles and porphyrins functionalized by several pyridyl groups. This electropolymerization process is based on a nucleophilic attack of the pyridyl groups onto electrogenerated ZnOEP dications at their meso-positions. It is the first time that bis-porphyrin copolymers have been obtained. In this study, the copolymers have been characterized by electrochemistry, UV-visible absorption spectroscopy and atomic force microscopy. In particular, interactions between pyridinium spacers are thoroughly discussed.

  通过使用锌β-八乙基卟啉（ZnOEP）类型的宏环和功能化了多个吡啶基团的卟啉，获得了五种双卟啉共聚合物，这一过程是通过电聚合方法实现的。该电聚合过程基于吡啶基团对电生成的ZnOEP二阳离子在其美索位点的亲核攻击。这是首次获得双卟啉共聚合物。在本研究中，这些共聚合物通过电化学、紫外-可见吸收光谱和原子力显微镜进行了表征。特别是，吡啶间隔物之间的相互作用得到了深入讨论。

  (ORR) formed via coordination-driven self-assembly have so far been limited to designs with fourfold symmetry, where four molecular clips bridge two porphyrin sites. We have synthesized six PynPhm (Py = pyridyl, Ph = phenyl) metalloporphyrin prisms (Co2+, Zn2+) bridged by molecular clips containing two Rh3+ centers. Four of these structures are lower symmetry, with the Py3Ph and Py2Ph2 prisms containing

  迄今为止，通过配位驱动自组装形成的用于氧还原反应 (ORR) 的共面卟啉催化剂仅限于具有四重对称性的设计，其中四个分子片段桥接两个卟啉位点。我们合成了六个 Py n Ph m（Py = 吡啶基，Ph = 苯基）金属卟啉棱柱体（Co 2+，Zn 2+ ），由包含两个 Rh 3+中心的分子片段桥接。这些结构中的四个具有较低的对称性，Py 3 Ph 和 Py 2 Ph 2棱柱分别包含三个和两个分子夹。钴2+评估了物种的 ORR 活性。水性介质中非均相催化剂墨水的循环和流体力学伏安法研究表明，对于 H 2 O 2的形成，选择性从～5% (Py 3 Ph) 到～37% (Py 2 Ph 2 ) 之间存在显着差异。Zn 2 Py 2 Ph 2的单晶X射线结构棱镜显示卟啉面之间的偏移。这种结构特征可能是选择性变化的原因，这与之前对共价连接的共面卟啉的研究一致，这些研究表明几何形状是双电子/双质子与四电子
