A series of novel styrylquinolines with the benzylidene imine moiety were synthesized and spectroscopically characterized for their applicability in cellular staining. The spectroscopic study revealed absorption ultraviolet–visible region (360–380 nm) emission that covered blue-green range light (above 500 nm). fluorescence quantum yields also determined, which amounted to 0.079 best-case scenario. structural features are behind these values discussed. An analysis properties theoretical...
New styrylquinoline derivatives with their photophysical constants are described. The synthesis was achieved via Sonogashira coupling using the newly developed heterogeneous nano-Pd/Cu catalyst system, which provides an efficient of high purity products. compounds were tested in preliminary fluorescent microscopy studies to order identify preferable cellular localization, appeared be lipid organelles. spectroscopic properties measured and theoretical TD-DFT calculations performed. A...
A new approach for the synthesis of acetylene‐substituted naphthalene diimides in polar solvents with PdCl 2 , Et 3 N, and electrolytic copper powder was developed. This simplified allows high‐throughput synthesis, reaction products can be readily separated. DFT studies revealed that electronic structures these compounds are mainly determined by central diimide unit acetylene groups. The obtained thermally stable soluble undergo reversible reduction electron affinities 4.18 to 4.28 eV. They...
A series of 3-amino-N-substituted-1,8-naphthalimides and their salicylic Schiff base derivatives were synthesized. The structure the obtained compounds was confirmed using 1H 13C NMR, FT-IR spectroscopy elemental analysis COSY HMQC for representative molecules. photophysical (UV–Vis, PL) biological properties all prepared studied. It found that amine with n-hexyl group in EtOH had highest PL quantum yield (Ф = 85%) compared to others. Moreover, chelating azomethines (1a, 1b, 1c) tested...
We recently described a novel class of thiosemicarbazones (TSCs) with high anticancer activity. Now, we expanded this compound library new TSCs 3-nitro-1,8-naphthalene unit. Thus, series TSC conjugates was obtained to determine the effect its chemical structure on spectroscopic properties, metal complexing and biological They were prepared in microwave reactor, provided compounds both yield purity. Nuclear magnetic resonance (1H 13C NMR, COSY, HMQC) infrared spectroscopy used characterize...
Abstract This paper presents the photophysical investigations of two organic compounds synthesised directly by aminolysis depolymerisation waste poly(ethylene terephthalate) (rPET) with aromatic amines, i.e., aniline and 3-amino-N-hexyl-1,8-naphthalimide without use a catalyst.
