Degradation by hydrolysis of three triphenylmethane dyes: DFT and TD-DFT study

نویسندگان

چکیده

DFT reactivity descriptors, the ultraviolet–visible spectra and hydrolysis mechanism of three cationic dyes [Malachite Green (MG), Brilliant (BG) Ethyl (EG)] are performed with several exchange–correlation functional (global GGA, hybrids range-separated). Using time-dependent density theory, theoretical absorption obtained obey trend for λmax: GGA > hybrid range-separated functional. Thanks to transition state barriers cation structures were in gas solution phase. It is shown that, these systems order: BG+ < MG+ EG2+ In two phases, CAM-B3LYP gives highest M06 lowest ones.

Optical signatures of borico dyes: a TD-DFT analysis

Using Time-Dependent Density Functional Theory (TD-DFT), we investigate the excited-state properties of a series of emissive dyes combining the properties of coumarins and fluoroborate compounds. These boron-iminocoumarins (borico) compounds have been synthesized very recently by Frath and coworkers [Chem. Commun., 49 (2013) 4908]. We determine both their vertical and 0-0 energies, reproduce an...

The solvatochromic, spectral, and geometrical properties of nifenazone: a DFT/TD-DFT and experimental study.

The solvatochromic, spectral, and geometrical properties of nifenazone (NIF), a pyrazole-nicotinamide drug, were experimentally and computationally investigated in several neat solvents and in hydro-organic binary systems such as water-acetonitrile and water-dioxane systems. The bathochromic spectral shift observed in NIF absorption spectra when reducing the polarity of the solvent was correlat...

Substituted diphenyl butadiynes: a computational study of geometries and electronic transitions using DFT/TD-DFT.

This work is aimed at theoretical understanding of electronic absorption and emission energies of a series of substituted diphenyl butadiynes through an assessment of several TDDFT functionals and a detailed study of solvent effects on their ground and excited state structures and properties. Out of a series of functionals examined, the coulomb attenuated DFT functional CAM-B3LYP is found to be...

Aza-boron-dipyrromethene dyes: TD-DFT benchmarks, spectral analysis and design of original near-IR structures.

The excited-state energies of aza-boron-dipyrromethene (Aza-BODIPY) derivatives are investigated with Time-Dependent Density Functional Theory (TD-DFT), with twin goals. On the one hand, a pragmatic, yet efficient, computational protocol is defined in order to reach rapidly semi-quantitative estimates of the λ(max) of these challenging dyes. It turned out that a PCM-TD-BMK/6-311+G(2d,p)//PCM-PB...

A TD-DFT investigation of UV spectra of pyranoı̈dic dyes: A NCM vs PCM comparison

We report the calculation of the UV spectra of more than 40 substituted coumarins and chromones in solution. In particular, two solvent models are compared, the multipolar expansion model (NCM) developed in Nancy and the PCM scheme developed in Pisa and Napoli. All calculations are carried out at the NCM-TDPBE0/6-311G(2d,2p)//NCM-B3LYP/6-311G(2d,2p) and at the PCMTDDFT/6-311+G(2d,2p)//PCM-DFT/6...
