The synthesis and fluorescence of N-substituted 1- and 2-aminopyrenes

The synthesis of N-derivatives of 3-aminoperylene and their absorption and fluorescence properties

“…This phenomenon is similar to that for N-triazinyl derivatives of aminopyrenes [4]. The strong fluorescence quenching of dichlorotriazinyl derivatives is the most remarkable feature.…”

“…Compound 3 was synthesized by treatment of 2 with acetic anhydride according to a literature procedure for synthesis of Nacetyl-2-aminopyrene with a slight modification [4]. The product was obtained in a high yield and purity.…”

“…In previous papers [2,3] we reported on the synthesis and solvent effect on absorption and fluorescence spectra, fluorescence lifetime and fluorescence quantum yield of N-triazinyl derivatives of 3-aminobenzanthrone. Recently, we have described spectral and photophysical characteristics of N-triazinyl derivatives of 1-and 2-aminopyrenes [4]. Presently we are studying the properties of the bichromophore of the D-T-A type with 3-aminoperylene as the EET acceptor.…”

The synthesis of bi- and trichromophoric dyes bearing an s-triazinyl ring spacer

“…Synthesis of 1-nitropyrene, 1-aminopyrene, N-(4,6-dichloro-1,3,5-triazin-2-yl)-1-aminopyrene (1) and N-(4,6-dichloro-1,3,5-triazin-2-yl)-3-aminobenzanthrone (4) was performed according to literature procedures [3,4].…”

“…Kapusta et al [3] and Šoustek et al [4] have reported on the synthesis and photo-physics of N-substituted 3-aminobenzanthrones and N-substituted 1-aminopyrenes respectively, i.e. of relevant component model compounds.…”
