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 synthesized π-extended systems have been studied by NMR spectroscopy, UV-

Fluorescent properties and the photoisomerization behaviour of 4-azulenylpyridine-substituted azobenzenes were investigated. All studied compounds have shown fluorescent emission in solution, originating from excited singlet state S2 → S0 of azulene moiety. The substitution of the azobenzene chromophore has affected the preservation of the fluorescence emission in thin films prepared in PMMA matrix. Correlation of absorption spectra with 1H-NMR spectroscopy revealed that for all compounds the E → Z isomerization takes place upon exposure to UV light.
