The azulene molecule features a unique combination of optical, luminescence, and stimuli-
responsive properties. This makes the azulene motif a promising functional group to be …

The nucleophilic aromatic substitution (SNAr) reaction of diethyl 6-bromoazulene-1, 3-
dicarboxylate (1) with a variety of amines afforded the corresponding 6-aminoazulene …

Covalent adducts of imidazole‐based mesoionic carbenes and nitrous oxide
(N2O,“laughing gas”) can be converted into azo dyes by reaction with arenes in the …

Four novel D-π-A extended styryl colorants containing carbazole unit were designed and
modified synthetically to evaluate the effect of various acceptors on ICT (intramolecular …

The present article deals with the synthesis, spectral characterization and antimicrobial
activity of phenylazo dyes. All of the synthesized phenylazo dyes were characterized using …

Highly conjugated azo-aromatic systems have been prepared in high to moderate yields by
linking mono-and bis-azo aromatic fragments to 4-(Rn-azulen-1-yl)-2, 6-dimethyl-pyridine …

The SNAr reaction of 2-chloroazulene derivative 1 with ethoxycarbonyl groups at the 1, 3-
