Synthesis and photolytic properties of 1,5-di-N,N′-dialkylaminoanthraquinones containing acryloyl groups
چکیده انگلیسی

Several l,5-di-N,N′-dialkyaminoanthraquinones containing acryloyl groups were synthesized and characterized by Fourier transform infrared (FTIR) and 1H NMR spectroscopy. The photophysical and photoinduction properties of these anthraquinone derivatives were examined in solution, in combination with free radical producing agents such as hexa-aryl-bis-imidazoles (HABI). When UV–vis absorption and fluorescence spectroscopy were employed to investigate the photophysical process, results showed that the photobleaching rate of N-alkylaminoanthraquinones containing an acrylate group and HABI was much faster than the acrylate group-free N-alkylaminoanthraquinone/HABI combination. N-alkylaminoanthraquinone induced polymerization of 2-phenoxyethyl acrylate (POEA)/N-vinyl carbazole (NVC)/cellulose acetate butyrate (CAB) mixtures was studied using real-time infrared spectroscopy (RTIR). It was found that the rate of polymerization was faster if the acryloyl groups were connected to the N,N′-dialkylaminoanthraquinone structure and that 1,5-di-N,N′-dialkylaminoanthraquinone containing acryloyl groups was more sensitive to visible light system.
