Substituted benzylideneanilines: A family of solvatochromic probes
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2019The solvatochromic behaviour of ten tailor-made structurally-related substituted N-benzylidineanilines was investigated in presence of solvents of varying polarities through inspection of UV-visible absorption spectra in the range 200 to 600 nm. The spectral bands were found to be significantly influenced by altering the polarity of the solvents. The o-

Vibrational Solvatochromism in Vaska’s Complex Adducts
The Journal of Physical Chemistry A, 2012The vibrational solvatochromism of bis(triphenylphosphine) iridium(I) carbonyl chloride (Vaska's complex, VC) was investigated by FTIR spectroscopy. The carbonyl stretching frequency (ν(CO)) was measured in 16 different organic solvents with a wide range of Lewis acidities for VC and its dioxygen (VC-O(2)), hydride (VC-H(2)), iodide (VC-I(2)), bromide (

Scope of negative solvatochromism and solvatofluorochromism of merocyanines
Physical Chemistry Chemical Physics, 2016Can negatively solvatochromic merocyanines retain their generic characteristics in the full range of solvent polarities including low-polarity alkanes? To find the answer, the solvatochromism of a vinylogous series of tailored highly dipolar merocyanines was thoroughly investigated both experimentally and theoretically.

Solvatochromic Shifts: A Reconsideration
The Journal of Physical Chemistry A, 1998Solvatochromic shifts in molecular spectra are often used to determine excited-state dipole moments. In comparing results with the more accurate gas-phase Stark effects studies, large discrepancies are obtained in the few cases in which both types of studies have been carried out. We attempt to reconcile the two techniques by reanalyzing solvatochromic

A solvatochromic chelating agent
Talanta, 1963Abstract 1-Methyl-2-[2-(8-hydroxy-5-quinolyl)vinyl]-8-hydroxyquinolinium chloride has been prepared as an example of a chelating agent for metals that changes colour with solvent polarity. As a chelating agent it has some selectivity, precipitating only the copper II ion in an acidic solution and forming a distinctively coloured product with zinc in
