Synthesis, Properties of a New (Polymer and Chalcone)

Abstract

This paper included two objectives: (i) Synthesis of Polymer {poly 2- [1- phenyl -3-(4-methyl phenyl)-4, 5-dihydropyrazole-5-yl-(4-phenoxy carbonyl)] styrene} PMDPCS and structure characterized by FT-IR, 1H-NMR spectra and Uv/Vis and XRD. (ii) Synthesis of chalcone {3-(4-(dimethylamino) phenyl)-2-phenyl-(2E) propen-1-one} (DAPPP) for absorption and fluorescence spectra under different solvents and concentrations. Also, under various concentrations, organic solvents and pump pulse energies of Nd: YAG laser, the amplified spontaneous emission (ASE) was studied. Additionally, under the same identical conditions, the amplified spontaneous emission spectra of DAPPP in solution were compared with a conventional laser dye of coumarin 503. Finally, the gain and the fluorescence quantum yield of DAPPP were determined.

Spectral and ASE Properties of 1-(4-Methylsulfonyl Phenyl)-3-(4-N, N Dimethyl Amino Phenyl)-2-Propen-1-One (MSPPP)

“…The above results have been compared with the spectral properties of 3-(4-(dimethyl amino) phenyl)-1phenyl-(2E)-propen-1-one (DAPPP) as a reference dye [3]. the absorption and uorescence spectra of DAPPP in acetone for different concentrations ranging from 0.65 to 6.5mM.…”

“…In the past few decades, studies on photophysical properties of organic uorescent compounds have been a subject of intensive investigation due to their increasing application in electronic and optoelectronic devices, biomedical imaging, and uorescence sensors [1][2][3][4][5]. The dye lasers based on rhodamine and coumarin derivatives are excellent laser media, but they have some shortcomings, such as a lack of photochemical stability [6][7][8].…”

Influence of Functional Groups on the Photophysical Properties of 1-(4-Methylsulfonyl Phenyl)-3-(4-n, n Dimethyl (amino Phenyl)-2-Propen-1-One Chalcone as Laser Dye

“…However, the photophysical properties depending on solvent environment and the influence of the FGs have not been fully studied. In earlier study, we showed that 3-(4-(dimethyl amino) phenyl) -2phenyl-(2E) -propen -1-one (C1) produced ASE under pulsed Nd: YAG laser excitation at 532 nm [14]. The result revealed that C1 has a large Stokes shift, an excellent photo stability, and high intensity lasing action (Scheme1).…”

“…In the past few decades, studies on photophysical properties of organic fluorescent compounds have been a subject of intensive investigation due to their increasing application in electronic and optoelectronic devices, biomedical imaging, and fluorescence sensors [1][2][3][4][5]. Chalcone derivatives are extensively used in optoelectronic fields such as photorefractive polymers [6], nonlinear materials [7], chromophore sensors [8], and in the study of photo-alignment layer of liquid crystal displays [9].…”

Structural and optical characteristic of 1-(4-Methylsulfonyl Phenyl)-3-(4-n, n Dimethyl (amino Phenyl)-2-Propen- 1-One (MSPPP) Chalcone doped ZnO nanoparticles

“…Chalcone derivatives have a functionality of a carbonyl group in conjugation with a carbon-carbon double bond, which is known as α, β-unsaturated keto group. The desirable properties of the chalcones are: adding/removing donor can modify high conjugation level; and the photophysical characteristics of these chalcones or acceptor groups the skeleton [13,14]. The doping of ZnO with other materials (heterostructures) has attracted significant interests from their predominant properties to combine two kinds of materials with lower photoexcitation threshold than individual components and decrease the recombination rate of electron-hole pairs by their physically separated band gap [15,16].…”
