“…On the other hand, for the negative solvatokinetic effect, molecular conformational changes may be the main reason for increasing the values of ϕ . For alcohols solvents, such as ethanol and methanol, the ability to form hydrogen bonds between the solvent and the solute leads to fluorescence quenching owing to the deactivation of the lone pair of -N(CH 3 ) 2 [ 38 ], elucidating the low values of ϕ in these solvents.…”

Two-Photon Absorption and Multiphoton Excited Fluorescence of Acetamide-Chalcone Derivatives: The Role of Dimethylamine Group on the Nonlinear Optical and Photophysical Properties

This work studied the effect of different electron-withdrawing and electron-donating groups on the linear and nonlinear optical properties of acetamide-chalcone derivatives. The results showed that the addition of the dimethylamine group led to a large fluorescence emission (71% of fluorescence quantum yield in DMSO solution) that can be triggered by two and three-photon excitations, which is essential for biological applications. Furthermore, dimethylamine also red-shifts the lower energy state by approximately 90 nm, increasing the two-photon absorption cross-section of the lower energy band by more than 100% compared with the other studied compounds. All compounds presented two-electronic states observed through one and two-photon absorption spectroscopy and confirmed by Quantum Chemistry Calculations (QCCs). QCC results were also used to model the experimental two-photon absorption cross-sectional spectrum by the Sum-Over-States (SOS) approach, revealing a dependence between the coupling of the ground state with the first excited state and the transition dipole moment between these states.

“…They found that DAP exhibits dual ASE bands at 545 and 565 nm under suitable pump power laser excitation and concentration. 100 The band at 565 nm could be attributed to the combination of two excited molecules and the solvent between them (superexciplex), and it is affected by the solvent polarity, concentration and pump power energies.…”

The paper reveals the spectrum and amplified spontaneous emission (ASE) features of a new Chalcone laser dye material of 1-(4-methylsulfonyl phenyl)-3-(4-N, N dimethyl amino phenyl)-2-propen-1-one (MSPPP) with the molecular formula C18H19NO3S. The absorption, fluorescence, Stokes’ shift, and quantum yield were obtained using different organic solvents. The energy band gap was calculated and compared with that of 3-[4-(dimethylamino) phenyl]-1-phenyl-(2E)-propen- 1-one (DAPPP). Under suitable concentrations and pump power excitation (Nd: YAG laser 355 nm), MSPPP produced an intense ASE at 522.5 nm. Previously, we had reported that DAPPP showed optical activities that were significantly better than that of coumarin 503. The absorption spectra of MSPPP showed a wavelength band in the range 403–427 nm, whereas the fluorescence spectra exhibited a band at 472–533 nm. ASE was observed under pump pulse laser excitation, and the wavelengths were attuned from 511 to 548 nm. The molecular geometry was optimized, and their HOMO-LUMO energy values were determined by SCM Software for Chemistry & Materials using the DFTB (GGA BLYP) [Density-Functional-Based Tight-Binding] method.
