Disclosed are surface immobilized (electro)catalysts that may be prepared by a condensation reaction that generates an aromatic unit that is robust to acid and base and elevated temperatures. Among their many desirable characteristics, the catalysts are far less prone to the bimolecular deactivation pathways commonly observed for homogeneous catalysts, and may be used in solvents with a range of polarities and dielectric strengths. The catalysts are suitable for a wide array of thermal catalytic reactions (polymerization, oxidation, hydrogenation, cross- coupling etc. ) and as anodes and or cathodes in fuel cells, electrolyzers, and in batteries and supercapacitors.

natural DNA structure. Thanks to their photophysical and photochemical properties, iridium(III) complexes are of increasing interest in the development of sensors and photoreactants for biochemical applications. In this view, we previously demonstrated that some IrIII complexes are able to photoreact with DNA through photoinduced electron transfer. In this study, we report the synthesis and characterization
基于 DNA 的纳米材料是众多研究的主题。合成了一系列修饰的核碱基,以构建双螺旋,其中天然 H 键合的碱基被金属配位的 liganosides 取代,或者在天然 DNA 结构中引入准时修饰。由于其光物理和光化学特性,铱 (III) 配合物在用于生物化学应用的传感器和光反应剂的开发中越来越受到关注。从这个角度来看,我们之前证明了一些 IrIII 复合物能够通过光诱导电子转移与 DNA 发生光反应。在这项研究中,我们报告了与其母体配合物相比具有未改变特性的带有铱配合物的核苷的合成和表征。
