Fluorescent-state switching of a 10-hydroxybezo h quinoline skeleton through the electronic nature of substituents

Key Points

• The aim is to control the excited-state geometry and ground-state basicity of a specific compound by altering substituents.
• Examined the effects of varying para-substituted phenyl groups at the 7- and 9-positions.
• Utilized spectroscopic analysis to assess excited-state properties.
• Analyzed ground-state basicity through chemical testing.
• Successfully modified the excited-state geometry using different para-substituents.
• Observed changes in ground-state basicity corresponding to substituent variations.
