Design, synthesis and nonlinear optical properties of (E)-1-(4-substituted)-3-(4-hydroxy-3-nitrophenyl) prop-2-en-1-one compounds

Nonlinear optical and spectroscopic properties, thermal analysis, and hemolytic capacity evaluation of quinoline-1,3-benzodioxole chalcone

“…1,4 Chalcones are a class of chromophoric organic compounds with several characteristics that make them suitable candidates for strong SHG generation. [4][5][6][7][8][9] These features include extended p-conjugation, non-centrosymmetric structure, enhanced nonlinear optical response, structural exibility, and nonlinear wave mixing capabilities (see Fig. 1).…”

“…In general, it has been proved that chalcones are a class of organic compounds that usually exhibit satisfactory NLO properties, with enormous potential in the design of optical devices, comparable and even superior to urea. 4,6 On the other hand, it has been understood that second-order molecular nonlinearity in chalcones can be enhanced by large delocalized p-electron systems with strong electron donor and acceptor groups. 4,5 The basic strategy of including electron donor and acceptor substituents to polarize the p-electron system of organic materials has been employed in the development of NLO chromophores with high rst and second order hyperpolarizabilities, good thermal stability, improved solubility and processability.…”

Synthesis and properties of some polyethers from chalcones

“…The linear absorption spectra of the chalcone derivatives recognized two strong peaks in the UV-region, which are due to π -π* and n -π* transitions, characterized for the presence of aromatic ring and C=O group, respectively. [21] N. Sharma also synthesized and antiplasmodial evaluated the vanillin derived allylated chalcones. [22] Four hydroxy-functionalized chalcones and their characterization using various spectroscopic techniques such as LC-MS, FT-IR, FT-Raman, fluorescence spectroscopy, thermogravimetric analysis, and UV-visible absorption spectroscopy were also reported by M. Jagadeesh et al [23] The authors suggested that the hydroxy-substituted chalcones exhibited strong dual emissions as a consequence of the locally excited states followed by internal charge transfer processes.…”
