Sažetak
Supramolecular gels based on low-weight molecules have attracted considerable research interest due to their potential applications in fields such as molecular electronics, lightenergy conversion, catalysis, cosmetics and drug delivery systems [1]. Coumarins are a very large class of compounds containing the unique 2H-chromen-2-one motif. Coumarin derivatives are widely found in nature, especially in plants and are components of several essential oils. The coumarin compounds are increasingly used in the design of smallmolecule fluorescent chemosensors because of its excellent biocompatibility, strong and stable fluorescence emission, and good structural flexibility [2]. In aim of design of fluorescent pseudopeptides, novel products containing coumarin chromophore linked via a triazole ring to an amino acid derivatives were synthesised using Cu-catalized “click” reaction. Their photophysical properties were fully investigated by UV-vis and fluorescence spectreoscopy. In all tested derivatives, excitation at 323 nm shows a wide band with a maximum of fluorescence at 389 nm. In addition to good fluorescent properties, synthesized triazolylcoumarin derivatives also show gelator properties, especially in the DMSO/H2O system, where fluorescent gels were obtained.
