Abstract
In this study novel fluorescence active, two triazine based thiazole derivatives, (2R,2'R)-2,4,6-triamine-N2-[2-(4-benzothiazolyl)phenyl]-N4,N6-[di(butan-1-ol)]-1,3,5-triazine and (1S,1'S,2R,2'R)-2,4,6-triamine-N2-[2-(4-benzothiazolyl)phenyl]-N4,N6-[di(1,2-diphenylethanol)]-1,3,5-triazine with chiral aminoalcohol groups were synthesized conveniently. Their enantiomeric recognition abilities toward the enantiomers of carboxylic acids such as mandelic acid and 2-chloromandelic acid were examined in DMSO/H2O (30:70) system using fluorescence spectroscopy. It was observed that DMSO solutions of chiral selectors showed no fluorescence emission while the emission increased 38 and 43 fold in 95% H2O for butan-1-ol and diphenylethanol derivatives, respectively similar with the aggregation-induced emission (AIE) characterized compounds. In the light of the experiment results, it was determined that the R-isomers of carboxylic acids formed more favourable complexes with the chiral selectors when compared to S-isomers.
