Abstract
Zadnjih godina triazoli su se pokazali obećavajuća svojstva u dizajnu i sintezi novih kemosenzorskih molekula za određivanje pH i iona metala zbog svoja tri dušikova atoma koji se mogu koristiti kao ligandi koji koordiniraju ione metala ili kao donori/akceptori vodikove veze. Otkriće bakrom (I) katalizirane azid-alkin cikloadicije (CuAAC), zajedno s drugim reakcijama, pojednostavilo je sintezu mnogih triazolnih kemosenzorskih molekula, a u ovom radu dan je pregled do sad istraženih senzora za metalne ione i pH koji su temeljeni na triazolima. U ovome radu napravljena je spektroskopska karakterizacija triju novih dušikovih heteroaromata kao potencijalnih kemijskih senzora. Primjenom UV/Vis i fluorescencijske spektroskopije, ispitan je utjecaj otapala različitih polarnosti na spektralna svojstva spojeva te ovisnost intenziteta fluorescencije spojeva 1, 2 i 3 o raznim ionima metala i pH vrijednosti s ciljem primjene spojeva kao potencijalnih pH ili metalnih senzora. Zbog promjene spektrofotometrijskih svojstava pri različitim koncentracijama Fe3+ i H+, spojevi 2 i 3 pokazuju potencijalna senzorska svojstva za detekciju iona željeza i pH.
Abstract (english)
In the recent years, triazole structures have shown promising properties in the synthesis and design of novel chemosensors and pH sensors due to their nitrogen atoms which can be used as metal ion coordinating ligands and donors/acceptors of the hydrogen bond. Discovery of the copper(I) catalyzed alkyne-azide cycloaddition (CuAAC), together with other reactions, simplified the synthesis of many triazole based chemosensing molecules. In this work, an overview of chemosensors for metal ions and pH based on the derivatives of triazole is given. This work presents the spectroscopic characterization of a novel triazole derivatives as potential chemosensors. The changes of the compounds' (1, 2 and 3) spectroscopic properties depending on the pH value and in presence of different metal ions, and also the effect of solvent polarity were studied by UV/Vis and fluorescence spectroscopy. Due to the change in spectroscopic properties in the presence of Fe3+ i H+ ions, compounds 2 and 3 exhibit potential iron and pH sensing properties.
