Growth, characterization and crystal structure analysis of 1-(4-chlorophenyl)-3-(4-chlorophenyl)-2-propen-1-one

Synthesis, growth, and characterization of 4-OCH3-4′-nitrochalcone single crystal: A potential NLO material

“…It has been shown that extended p systems with terminal donor-acceptor substituents exhibit large b values [3,4]. In these categories, chalcone derivatives are attracting a great deal of attention due to their high NLO coefficients [5][6][7][8][9], and good crystallizability [10][11][12]. As observed in our laboratory [13,14], single crystal structures of two such NLO crystals of chalcone, 1-(4-bromophenyl)-3-(2,4-dichlorophenyl) prop-2-en-1-one (2,4-DiCL-4 0 -bromochalcone), and 3-(2,4-dichlorophenyl)-1-(4-methylphenyl) prop-2-en-1-one (2,4-DiCL-4 0 -methylchalcone), possess a second harmonic generation (SHG) conversion efficiency of about 1.5 and 1.2 times that of urea, respectively.…”

Synthesis, crystal growth, characterization and structure–NLO property relationship in 1,3-bis(4-methoxyphenyl)prop-2-en-1-one single crystal

“…The SHG efficiency of BMP was comparable with that of urea. BMP has the same magnitude of SHG efficiency as 1-(4-methylphenyl)-3-(4-N,N dimethyl amino phenyl)-2-propen-1-one [23], better SHG efficiency than 1-(4-chlorophenyl)-3-(4-chlorophenyl)-2-propen-1-one [24] and twice that of 1-(4-methylphenyl)-3-(4-methoxyphenyl)-2-propen-1-one [25].…”

Vibrational spectra analysis, NBO, HOMO–LUMO, and nonlinear optical behavior studies on 3-(3,4-dimethoxyphenyl)-1-(pyridin-2-yl)prop-2-en-1-one

“…These compounds have attracted increasing attention due to numerous pharmacological applications [3][4][5][6]. These compounds exhibit good second harmonic generation (SHG) efficiency, excellent blue light transmittance [7,8], good crystallizability [9][10][11][12], better optical limiting behavior with nanosecond laser pulses at 532 nm wavelength [13], and ultrafast optical nonlinearities at 780 nm [14]. Studies on chalcones suggest that the secondorder molecular nonlinearity can be enhanced by large delocalized p-electron systems with strong donor and acceptor groups [15].…”
