“…Fluorescent and UV-vis spectra of these derivatives were measured with a FLSP920 and HITACHI U3010 spectrophotometers. Tris(4-((trimethylsilyl)ethynyl)phenyl)amine (1), tris(4-ethynylphenyl)amine (2), 2-(4-bromophenyl)-1-phenyl-1H-benzo [d]imidazole (3), and 2-(3-bromophenyl)-1-phenyl-1H-benzo [d]imidazole (4) were synthesized following the method reported in the literature [13].…”

“…TPA based D-π-A framework have attract much more attention as the best electron transporting organic materials in dye sensitized solar cell (DSSC) due to their in expensive synthesis, outstanding stabilities, and high molar extinction coefficient [12][13][14][15][16][17][18]. A large number of TPA based chromophores are used for their applications in red to deep red organic light emitting diodes (OLEDs) [19][20][21][22][23][24][25][26]. The TPA has excellent intramolecular charge transfer (ICT) characteristics and it is attached to different electron withdrawing units for various applications [27][28][29][30][31][32][33][34].…”

Four small dyes with triphenylamine (TPA) as a donor and various acceptor groups connected with π-linker having chloro group are synthesized and studied for solvatochromism and DFT. Good solvatochromism is observed in compounds 2 and 4 having TPA attached to rhodamine-3-acetic acid and 4-aminosalicylic acid. The multilinear regression analysis supports the solvatochromic behaviour of the chromophores. The compound 4 shows viscosity sensing with 0.57 viscosity sensitivity (x) value as which is more as compared with the other compounds, and 14.14-fold increased emission intensity in viscous solution from 0 to 99% of PEG-400 in ethanol. These TPA based compounds 1, 2, 3, and 4 show two-photon absorption cross section in the range 702-1265 GM. The natural bond analysis shows charge transfer in compound having strong withdrawing groups, that is compound 1 and 2. The bond length alteration is correlated with the computationally obtained NLO properties and show linear correlation. The compound 1 is a better NLOphoric material than the other compound 2, 3, and 4 as revealed by solvatochromic and computational methods.

“…One of the branches of this progress is the development of new organic light-emitting diodes (OLEDs) [1,2], which are now widely used in industry and everyday life. OLEDs have a layered structure, in which each of the layers performs a certain function and frequently consists of polymer or oligomer material [3][4][5][6][7]. The advantage of oligomers is that they possess properties of corresponding polymers to a large extent but, in contrast to the latter, oligomers can be more easily chemically modified.…”

Quantum-chemical investigation of the structure and electronic absorption spectra of symmetric triphenylamine oligomers conjugated to vinylene, imine, azine, and ethynylene groups

Based on the density functional theory (DFT) and using the B3LYP and BMK hybrid exchangecorrelation functionals, we have studied the structure and electronic-spectral properties of some triphenylamine oligomers that contain various π-electron spacers of end groups and that are of interest as electro-and photoactive materials. Good agreement between calculation results and experimental data on absorption spectra in the visible and UV ranges has been obtained. The nature of visible spectral bands has been elucidated based on interrelations with structural changes of oligomer molecules.
