  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。
