Abstract
S ciljem da se ispita kompleksacijski afinitet miješanog difenilantracenskog i esterskog derivata kaliksarena (5,11,17,23 tetra-tert-butil-25-(9,10-difenilantracen-2-iloksietoksi)-26,27,28- tris(etiloksikarbonilmetoksi)-kaliks[4]aren), K, prema odabranim organskim spojevima - rodaminu B, auraminu O i fluoresceinu te timokinonu, proveden je niz spektrofotometrijskih titracija u smjesi otapala acetonitril/diklormetan (φ = 0,5:0,5). Na temelju eksperimentalnih podataka dobivenih spektrofotometrijskim titracijama zaključeno je da ovaj kaliksarenski derivat od svih ispitivanih spojeva najveći afinitet pokazuje prema fluoresceinu pri čemu nastaje kompleks čija konstanta stabilnosti iznosi log (K [K-fluorescein] / mol dm -3 ) = 2,89 ± 0,01. S auraminom O i rodaminom B primijećeno je stvaranje intramolekulskih interakcija, međutim one su vrlo slabe i ne vode do stvaranja stabilnih kompleksa. Naposlijetku, za timokinon nije uočena nikakva interakcija sa spojem K. Razmatranjem strukturnih karakteristika ovih spojeva, zaključeno je da najveći doprinos stabilizaciji kompleksa imaju vodikove veze koje se uspostavljaju između molekule gosta i karbonilne skupine kaliksarena.
Abstract (english)
To examine the complexation affinity of the mixed diphenylanthracene and esther derivative calixarene (5,11,17,23-tetra-tert-buthyl-25-(9,10-diphenylantracene-2-yloxyethoxy)-26,27,28-tris(ethyl- oxicarbomilmehtoxy)-kalix[4]aren), K, towards the selected organic compounds: rhodamine B, auramine O, thymoquinone and fluorescein, a series of spectrophotometric titrations were carried out in acetonitrile/diphenylantracene solvent mixture (φ = 0.5:0.5). Based on the experimental data obtained by spectrophotometric titrations it was concluded that out of all studied compounds this calixarene derivative shows the highest affinity towards fluorescein, whereby a complex, whose stability constant is log (K [K- fluoresceine] / mol dm -3 ) = 2.89 ± 0.01 is formed. The formation of intramolecular interactions was observed for auramine O and rhodamine B, however, these interactions were very weak and did not lead to the formation of a stable complexes. Finally, no interaction of compound K with thymoquinone was observed. Taking into consideration the structural characteristics of these compounds, it was concluded that the greatest contribution to the stabilization of the complexes is through hydrogen bonds established between the guest molecule and the carbonyl group of the calixarene derivative.
