Abstract

Push-pull sustavi su molekulske strukture u kojima se naboj prenosi s elektron-donorske jedinice na elektron-akceptorsku preko poveznice. Takvi sustavi mogu biti korišteni kao optički senzori. Aromatski triazoli često se upotrebljavaju kao π-konjugirane poveznice u procesima intramolekularnog prijenosa naboja unutar push-pull molekulskih struktura. U ovom radu dan je pregled heterocikličkih push-pull kromofora s 1,2,3-triazolnom poveznicom i kumarinskom skupinom. Da bi se omogućilo bolje razumijevanje navedenog procesa predložena je sinteza klase spojeva koji sadrže kumarinsku jezgru i različite donorske ili akceptorske aromatske funkcionalne skupine među kojima je 1,2,3-triazolna poveznica. U tu svrhu provedena je sinteza jednog od predloženih spojeva azid-alkin cikloadicijom kataliziranom bakrom(I).

Abstract (english)

Push-pull systems are molecular structures in which charge is transmitted from electron-donor unit to electron-acceptor unit via linker. Those kind of structures can be later utilized as optical sensors. Aromatic triazoles are frequently used as π-conjugated linkers in intramolecular charge transfer processes within push-pull systems. This paper presents an overview of the heterocyclic push-pull cromophores incorporating 1,2,3-triazole linker and coumarin moiety. In order to provide a better understanding of intramolecular charge transfer the synthesis of series of compounds containing coumarin core and various donor or acceptor aromatic functional groups, including 1,2,3-triazole linker, is suggested. For that purpose, one of the proposed compounds was synthesized by the copper(I)-catalyzed azide-alkyne cycloaddition.
