The research focuses on the synthesis, spectral, and luminescence properties of anthracene derivatives of benzo[f]quinoline. The key chemicals involved in the research include 9-[N-(2-naphthyl)formimidoyl]anthracene, various methyl ketones such as acetophenone and substituted acetophenones, and other reagents like concentrated HCl, butanol, nitrobenzene, and 2-naphthylamine hydrochloride. The synthesis process involves condensation reactions under acid catalysis, leading to the formation of l-R-3-(9-anthryl)benzo[f]quinolines and byproducts like l-R-3-(9-anthyl)-2-propen-l-ones and N-[l-(p-aminophenyl)-3-(9-anthryl)-2-propen-l-ylidene]-2-naphthylamines. The spectral properties of these compounds were examined using IR, UV, and mass spectrometry, while their luminescence characteristics were assessed through fluorescence spectra and quantum yield measurements. The study highlights the significant contribution of the anthracene ring to the light absorption capabilities of these molecules and investigates the influence of different substituents on their luminescence behavior.
