Synthesis and nonlinear optical absorption of novel chalcone derivative compounds

Synthesis, photophysical properties and DFT analysis of highly substituted pyrido carbazole-based “push pull” chromophores

“…6 Organic compounds containing both electron donating (D) and accepting (A) substituents in a single molecule, exhibit interesting optical and spectral properties due to intramolecular charge transfer (ICT). This phenomenon has long been a topic of great interest in photochemistry owing to fundamental scientific value 7 as well as potential applications in photoelectronic and nonlinear optical devices, 8,9 and understanding photochemical and photobiological processes. 10 ICT is particularly important in fluorescent compounds which act as polarity probes or ionophores.…”

New 1,2,3-triazole linked ciprofloxacin-chalcones induce DNA damage by inhibiting human topoisomerase I& II and tubulin polymerization

“…Both new compounds and their intermediates were synthesised as drawn in Scheme 1 . In particular, the intermediate 1-(4-azidophenyl)ethanone 1 was prepared following the previously published procedures 65 , 66 . Chalcone derivatives 2a-j were synthesised by condensation of 1-(4-azidophenyl)ethanone 1 with the appropriate aromatic aldehyde in ethanol in presence of sodium hydroxide 65 , 66 .…”

Synthesis, optical properties, laser activity and DFT studies of (E,E)-2,5-bis[2-(1-methyl-1H-pyrrole-2-yl)-vinyl]pyrazine (BMPVP)

“…Organic molecules containing both electron donating (D) and accepting (A) substituents, in a single molecule, exhibit interesting optical and spectral properties due to intramolecular charge transfer (ICT). This phenomenon led to substantial research owing to potential applications in photoelectronic and nonlinear optical devices [5,6], chemical sensing [7], and understanding photochemical and photobiological processes [8].…”
