Crown ether cyanine dye precursors I (R = Et, CH2CH2OH; X = I, Cl, (CH2)3SO3) were prepared and characterized by elemental anal., NMR, and IR spectroscopy. The unquaternized I was prepared by cyclization of 4,5-dinitrobenzo-15-crown-5 in the presence of AcOH followed by ethylation in the presence of KOH.

Key words: BENZIMIDAZOLE P, CROWN ETHER COMPOUNDS, QUATERNARY AMMONIUM COMPOUNDS, CYANINE DYES
