4-Alkoxynaphthaldehydes and their application in synthesis of styryl pyrylium dyes with broad absorption band in visible spectrum
Published: 19 November 2008 by MDPI in The 12th International Electronic Conference on Synthetic Organic Chemistry session General Organic Synthesis
Abstract: 2,4-Di(4-propoxyphenyl)-6-(4-propoxynaphthyl)pyrylium tetrafluoborate - styryl pyrylium dye with broad absorption bands at 400-500nm and 500-630nm was synthesized. Method for obtaining intermediate 4-propoxynaphthaldehyde was improved.
Keywords: pyrylium salt, styryl pyrylium dye, 4-alkoxynaphthaldehydes
