    Abstract Iodination of thiophene derivatives is realized using a simple, fast, and efficient methodology. Iodination of thiophene and 2- or 3-substituted or 3,4-disubstituted thiophenes with N-iodosuccinimide (NIS) activated with 4-toluenesulfonic acid in ethanol gives pure iodinated products that require no further purification.

    coupling of the ferrocenyl and the thiophene moieties has been realized using the Negishi C,C cross-coupling reaction protocol. Compounds 3a and 4c were structurally characterized by single-crystal X-ray diffraction studies. In electrochemical measurements the ferrocenyl redox potential depends on the particular substitution at the ferrocenyl and the thiophene unit. Moreover, UV/Vis/NIR studies showed ligand-to-metal
    UV/Vis/NIR 研究表明配体-金属电荷转移 (LMCT) 相互作用,这种相互作用发生在氧化后,随着供体-受体能隙的减小而发生红移。使用具有吸电子或供电子能力的不同取代基,可以调整二茂铁受体单元和供电子噻吩系统之间的能量差。
