The π→ π* transitions of more than 100 organic dyes from the major classes of
chromophores (quinones, diazo,...) have been investigated using a Time-Dependent …

The effect of the solvent polarity parameters f (Ɛ, n) and ᵩ (Ɛ, n) appearing in
solvatochromic theories, and the effect of the molecular shape of the Onsager cavity (sphere …

A set of three donor–acceptor azahelical coumarins (DA-AHC s), namely, H-AHC, Me-AHC,
and Ph-AHC, were rationally designed and synthesized, and their excited-state properties …

The effect of solvents on absorption and fluorescence spectra and dipole moments of
coumarin 307 (C307) and coumarin 522B (C522B) have been studied extensively in various …

Aryl alcohol‐type or phenolic fluorophores offer diverse opportunities for developing
bioimaging agents and fluorescence probes. Due to the inherently acidic hydroxyl …

Using time-dependent density functional theory (TD-DFT) and the polarizable continuum
model, we have computed the electronic transitions of a large panel of coumarin dyes in …

In the presented study, advanced experimental techniques, including electronic absorption
and fluorescence spectroscopies [with Resonance Light Scattering (RLS)], measurements of …

The optical properties of Malachite green (Mg) dye were examined experimentally, including
absorption, optical energy gab, refractive index, dielectric constant, optical conductivity and …

New quinoline-3-carbonitrile derivatives were synthesized and evaluated for their potential
antibacterial behavior. Compounds were obtained by a one-pot multicomponent reaction of …

A dye mixture of Disperse red1 (DR1) and Janus green B (JGB) was prepared with different
concentrations of the two dyes. The optical properties were studied for the two dyes and their …
