The construction of thiophene-fused analogues of diboraanthracenes with different aryl substituents through boron-mercury exchange followed by the nucleophilic replacement of the chlorines of dichlorodiboradithiophene 2 with Grignard reagents is reported. These diboradithiophenes exhibited unusual photophysical and electrochemical properties. They all undergo photoisomerisation, which can be traced using photophysical and 1H NMR spectroscopy studies.

噻吩融合的硼环作为二硼蒽的光活性类似物

据报道,通过硼-汞交换,然后用格氏试剂对二氯硼二噻吩2的氯进行亲核置换,构建了具有不同芳基取代基的二硼蒽的噻吩稠合类似物。这些二硼二噻吩表现出不寻常的光物理和电化学特性。它们都经历了光异构化,可以使用光物理和1 H NMR 光谱研究进行追踪。
