In 1970, three laboratories independently made a discovery that, for aromatic fluorophores
embedded into different rigid and highly viscous media, the spectroscopic properties do not …

In recent experiments, a novel chromophore (N, N,-bis (salicylidene)-(2-(3 ″4′-
diaminophenyl) benzothiazole)(BTS)) with double hydrogen bond structure was …

Abstract After the synthesis of 2-(2-carbonmethoxy-3, 4-dichloro-6-hydroxyphenyl)(
Compound 1), Elena V. Vetrova et al. found that it has different photophysical phenomena in …

Internal Stark effect (or internal electrochromy) consists of the shift of light absorption and
emission bands under the influence of electric field produced by proximal charges. In the …

3-Hydroxychromones (3HCs) are fluorescent dyes, which respond to solvent perturbations
by shifts and changes in the relative intensity of the two well-separated bands in the …

Different substituents and benzene ring numbers had significant effects on the fluorescence
phenomenon of 2-aryloxazoline derivatives as observed in an experiment. Here, we select …

Picosecond time-resolved fluorescence spectroscopy has been applied to the studies of
excited-state intramolecular proton transfer (ESIPT) dynamics in two 4 '-(dialkylamino)-3 …

The proton transfer reaction in methyl 5-R-salicylate is found to be highly sensitive to the
presence of specific substituents in resonance with the hydroxyl group, leading to different …

Recently, the researchers found that the large ring benzimidazoles chromophores are prone
to deprotonation to form double ion holes, which can strongly bind with organic cations. The …

The spectroscopic behavior of the 4 '-dialkylamino-3-hydroxyflavones in protic environments
is very unusual. Previous studies showed that in contrast to other solvatochromic dyes …
