Several 1-azulenyl vinyl crown ethers were synthesized starting from (1-azulenylmethyl) triphenylphosphonium iodide and 4-formylbenzo-crown ethers in the Wittig reaction conditions. The reaction worked in fair conditions and the obtained mixtures of geometric isomers were separated using column chromatography. The isomers were identified using H-NMR spectra and the mass spectra were recorded using ESI. The UV-vis spectra showed bathochromic effect in Z isomer compared with the E one.
