摘要: 合成了5种不对称冠醚碲碳菁染料。对合成关键中间体冠醚苯并碲唑所用的4-硝基苯并15-冠-5的还原酰化方法进行了改进,比较和研究了杂原子在同一主族的4个菁染料的可见吸收光谱,计算了它们的“Brooker偏差”。

关键词: 冠醚碲碳菁染料, 合成, 吸收光谱

Abstract: Five asymmetric crown telluracarbocyanines were prepared. The visible absorption spectra and the “Brooker diviation” of four of them have been studied. The method of reduction and acylation of 4-nicrobenzo-15-crown-5-has been improved, making the synthesis of the asymmetric crown ether telluracarbocyanine dyes quite convenient and easy.

Key words: crown ether telluracarbocyanine, synthesis, absorption spectrum
