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”
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 4nicrobenzo15crown5 has been improved, making the synthesis of the asymmetric crown ether telluracarbocyanine dyes quite convenient and easy.
