摘要 Two Crown ether benzotellurastyryl cyanines and three crown ether benzotelluramerocyanines are synthesized via the key intermediate 3 methyl 5,6(15 crown 5) 2(β acetanilide)vinyl benzotellurazolium iodide.The reactive conditions are discussed.The influence of alkali( earth)metal ions on the visible absorption spectra of these two types of crown ether cyanines are also studied.
