摘要：The synthesis of furyl, thienyl and indole methine dyes derived from N-substituted-3-cyano-4-methyl-6-hydroxyl-2-pyridones has been achieved by condensation of pyridones with heteroaryl aldehydes. In addition, 5-amino-3-cyano-4-methyl-6-hydroxyl-1-ethyl-2-pyridone was synthesized and nitrosated to give an azamethine dye. The absorption properties of these novel cyanine dyes were investigated in various solvents. (C) 2001 Elsevier Science Ltd. All rights reserved.
