Abstract
U ovom završnom radu dan je teorijski uvid u supramolekulsku kemiju, kaliksarene i fluorimetriju te njihovu primjenu. Eksperimentalno je fluorimetrijskim titracijama istraživano koji od kationa elemenata iz zemnoalkalijske skupine ima najveći afinitet za stvaranje kompleksa s fenantridinskim derivatom kaliksarena5,11,17,23-tetra-tert-butil-25,27-bis(6-fenantridinilmetiloksi)-26,28- dimetoksikaliks[4]arenom, L. Zbog slabe topljivosti spoja L u polarnom otapalu, korišten je sustav otapala acetonitril/diklormeta, a od kationa su korišteni: magnezijev, kalcijev, stroncijev te barijev kation. Na temelju dobivenih eksperimentalnih podataka fluorimetrijskom titracijom zaključeno je da ligand L od svih spojeva najbolje kompleksira s kationom barija, odnosno prema njemu ima najveći afinitet pri čemu nastaje kompleks čija konstanta stabilnosti iznosi logK / dm 3 mol -1 = 4,90 ± 0,01.Od svih ispitivanih kationa, jedino za stroncijev kation s ligandom L fluorimetrijski nije uočeno stvaranje kompleksa. Utjecaj solvatacije i ionskog sparivanja imao je znatan utjecaj na afinitet kationa prema kompleksiranju s ligandom L, što se reflektira i u vrijednostima dobivenih konstanti stabilnosti odgovarajućih kompleksa, a pri tom veličina kationa ima važnu ulogu i za jačinu solvatacije i stvaranje ionskih parova, kao i za stabilnost kompleksa.
Abstract (english)
This thesis provides a theoretical insight into supramolecular chemistry, calixarenes, and fluorimetry as well as their applications. It was experimentally investigated by fluorimetric titrations which of the cations of elements from the alkaline earth group has the highest affinity for the formation of a complexe with the phenanthridine derivative of calixarene 5,11,17,23-tetra-tert-butyl-25,27-bis(6- phenanthridinylmethyloxy)-26,28 -dimethoxycalix[4]arene, L. Due to the poor solubility of compound L in polar solvents, the solvent system acetonitrile/dichloromethane was used, while magnesium, calcium, strontium, and barium were used as cations. Based on the obtained experimental data by fluorimetric titration, it was concluded that, among the studied cations, ligand L has the highest affinity towards the barium cation, resulting in a complex whose stability constant is log K / dm 3 mol -1 = 4.90 + 0,01. Of all the tested cations, only for the strontium cation with the ligand L the formation of a complex was not observed fluorimetrically. The influence of solvation and ion pairing had a significant effect on the affinity of cations towards complexation with ligand L, which is reflected in the values of the obtained stability constants of the corresponding complexes, while the size of the cation plays an important role in the strength of solvation and formation of ion pairs, as well as in the stability of the complex.
