Photophysical Behavior and Sensing Response of Chalcone Containing Pyrene moiety [PDF]
D–π–A dye composed of pyrene and thiophene units was synthesized and characterized using elemental, FT-IR, and mass analyses. The solvatochromic response was investigated in different solvents of various polarities.

Preferential solvation of quercetin in aqueous aprotic solvent mixtures [PDF]
Solvatochromism of quercetin was studied in binary mixtures of water with dimethyl sulfoxide, N,N-dimethylformamide and N,N-dimethylacetamide at 25 °C by UV–Vis measurements.

Solvatochromic covalent organic frameworks [PDF]
AbstractCovalent organic frameworks (COFs) are an emerging class of highly tuneable crystalline, porous materials. Here we report the first COFs that change their electronic structure reversibly depending on the surrounding atmosphere. These COFs can act as solid-state supramolecular solvatochromic sensors that show a strong colour change when exposed ...

Prediction of Strong Solvatochromism in a Molecular Photocatalyst**
Abstract Based on quantum chemical calculations, we predict strong solvatochromism in a light‐driven molecular photocatalyst for hydrogen generation, that is we show that the electronic and optical properties of the photocatalyst strongly depend on the solvent it is dissolved in.

Solvatochromism and the solvation structure of benzophenone [PDF]
Many complex molecular phenomena, including macromolecular association, protein folding, and chemical reactivity, are determined by the nuances of their electrostatic landscapes. The measurement of such electrostatic effects is nonetheless difficult, and is typically accomplished by exploiting a spectroscopic probe within the system of interest, such ...
