Abstract

Four symmetrical and asymmetrical pyrylium-squarylium cyanine dyes were synthesized. Their structures were confirmed by spectroscopy and element analysis. Absorption spectra, melting points and solubilities were studied. It was revealed that pyrylium-squarylium cyanine dyes had longer absorption wavelength and better solubilites than other squarylium cyanine dyes. The unusual melting points were explained by Dye 2 single crystal packing structue.

Key words: PYRYLIUM SALT, SQUARIC ACID, CYANINE DYES, SOLUBILITY, ULTRAVIOLET SPECTROPHOTOMETRY, ELEMENTAL ANALYSIS
