    Carbon Nanotube-Templated Synthesis of Covalent Porphyrin Network for Oxygen Reduction Reaction
    摘要:
    The development of innovative techniques for the functionalization of carbon nanotubes that preserve their exceptional quality, while robustly enriching their properties, is a central issue for their integration in applications. In this work, we describe the formation of a covalent network of porphyrins around MWNT surfaces. The approach is based on the adsorption of cobalt(II) meso-tetraethynylporphyrins on the nanotube sidewalls followed by the dimerization of the triple bonds via Hay-coupling; during the reaction, the nanotube acts as a template for the formation of the polymeric layer. The material shows an increased stability resulting from the cooperative effect of the multiple pi-stacking interactions between the porphyrins and the nanotube and by the covalent links between the porphyrins. The nanotube hybrids were fully characterized and tested as the supported catalyst for the oxygen reduction reaction (ORR) in a series of electrochemical measurements under. acidic conditions. Compared to similar systems in which monomeric porphyrins are simply physisorbed, MWNT-CoP hybrids showed a higher ORR activity associated with a number of exchanged electrons close to four, corresponding to the complete reduction of oxygen into water.

    摘要:
    为了改善中央卟啉核心与其外围芴基触角之间的共轭作用,我们在中位四芴基卟啉(TFP-Bu)单元的中位引入了乙炔基间隔物。通过这种方法,我们合成并鉴定了一种新的中-炔基芴卟啉(TAFlP)。我们讨论了[式中:见正文]流形的这种额外扩展对光学特性的影响。这种扩大的卟啉核心 TAFlP 被认为是设计治疗应用新型树状分子的关键构件。本文回顾了以共轭芴基树枝为特征的卟啉基树枝形分子的不断改进,证明了中心核结构在决定线性和非线性光学特性方面的重要作用。根据对最近获得的树枝状聚合物的观察,类似 TAFlP 的结构似乎有可能进一步改善这些特性。因此,探索这种新的分子结构对于光动力疗法(PDT)和相关应用具有吸引力。

  • Meso-alkynyl porphyrins
    作者:Harry L. Anderson

    日期:1992.2
    Porphyrins with meso-alkynyl substituents have been synthesised from trimethylsilyl propynal. Their red-shifted UV spectra and unusual reactivity towards nucleophiles indicate that there is good overlap between the porphyrin pi-systems and the triple bonds.
