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 4nicrobenzo15crown5 has been improved, making the synthesis of the asymmetric crown ether telluracarbocyanine dyes quite convenient and easy.
