Five newly synthesized bent-shaped compounds containing azobenzene chromophores have been prepared by
resorcinol esterification with 4-(4-alkyloxyphenylazo) benzoic acid using DCC and DMAP. The structure of newly synthesized
compounds was confirmed by MS and FT-IR spectroscopy. In addition, NMR spectroscopy also established the
purity of these compounds. According to their azo-type chemical structure, the newly synthesized compounds are expected
to be highly fluorescent. Consequently, their absorption and fluorescence properties were investigated using UVVis
and fluorescence spectroscopy. The present paper also investigates the fluorescence evolution of glycyl-L-tryptophan
dipeptide at different concentrations of the newly synthesized bent-shaped compounds. The intensity of their fluorescence
band over 400 nm depends much on individual structures. Since the investigated compounds could have optical properties
characteristic to liquid crystals, the interaction with fluorescent peptides, such as glycyl-tryptophan or proteins might enhance
their utility.
