2-Substituted 6-, 7- or 8-methoxyquinoline-4-carboxylic acid derivatives were synthesized. The fluorescence quantum yield (Φ) of these compounds increased in the order, 2-thioxo-, 2-methylthio-, 2-methylsulfinyl-, 2-methylsulfonyl derivatives of 6-methoxyquinoline-4-carboxylic acid. Ethyl 6-methoxy-2-methylsulfonylquinoline-4-carboxylate (Φ(CH3CN) = 0.74 or Φ(EtOH) = 0.69) showed a much higher fluorescence quantum yield than those (Φ(CH3CN) = 0.19 or Φ(EtOH) = 0.19 and Φ(CH3CN) = 0.16 or Φ(EtOH) = 0.05) of the 7- and 8-methoxy derivatives in both acetonitrile and ethanol.
