Abstract The paper presents synthesis and characterization of
azobenzene compound that contains 10 carbon atoms as flexible terminal chain
and one fluorine atom as lateral polar substituent. The synthesis was
achieved by diazotization of 4-amino benzoic acid and coupling of diazonium
salt to 2-fluorophenole, followed by alkylation with a bromoalkyl compound.
The synthetized compounds were purified and their structures were confirmed
by 1H-NMR and 13C-NMR studies. Keywords: diazotization, coupling,
fluorine, alkylation.
