Luminiscenčne lastnosti cinkovih koordinacijskih spojin z indol-3-propionatnim in indol-3-acetatnim ligandom z nevtralnimi dušikovimi ligandi

Setnikar, Luka (avtor), Perdih, Franc (mentor)

V sklopu magistrske naloge sem sprva sintetiziral spojini [Zn(I3P)2] in [Zn(I3O)2]. Pri sintezi obeh navedenih spojin sem kot izhodno spojino uporabil ZnCl2 in ustrezno kislino (indol-3-propanojsko (I3P-H) in indol-3-ocetne kislino (I3O-H)). Pripravljeni spojini sem nato uporabil kot izhodni spojini pri sintezah z različnimi nevtralnimi dušikovimi ligandi. Sinteze sem izvajal v dveh množinskih razmerjih med izhodno spojino cinka in ligandom (1:1 in 1:2), ob uporabi različnih topil (metanol, etanol, kloroform, voda, aceton, dimetilformamid) v različnih kombinacijah. Nastale produkte sem okarakteriziral z analizo razultatov nekaterih fizikalno-kemijskih metod (rentgensko praškovna analiza (PXRD), rentgenska analiza monokristala (XRD), jedrska magnetna resonanca (1 H NMR). Posnel sem tudi IR spektre, UV-Vis in luminiscenčne spektre produktov v trdnem. Z uporabo navedenih metod sem predvidel sledeče formule dobljenih spojin: [Zn(I3P)2(2,2'-bipy)] (2,2'-bipy = 2,2'-bipiridin), [Zn(I3O)2(4,4'-bipy)], [Zn(I3P)2(4,4'-bipy)] (4,4'-bipy = 4,4'-bipiridin), [Zn(I3O)2(4-ampy)2]∙H2O (4 ampy = 4-aminopiridin), [Zn(I3P)2(bipyam)] (bipyam = 2,2'-bipiridilamin), [Zn(I3P)2(phen)] (phen = 1,10-fenantrolin), [Zn(I3P)2(neo)], [Zn(I3O)2(neo)] (neo = neokuproin).

As a part of my master thesis [Zn(I3P)2] and [Zn(I3O)2] were initially synthesized from ZnCl2 and the corresponding acid (indole-3-propanoic and indole-3-acetic acid). Those two compounds were used as starting compounds in syntheses with various neutral nitrogen ligands. Syntheses were performed in two mass ratios between the initial zinc compound and the ligand (1:1 and 1:2), using different solvents (methanol, ethanol, chloroform, water, acetone, dimethylformamide) in different combinations. The resulting products were characterized by analyzing the results of some methods (X-ray powder analysis (PXRD), single crystal X-ray analysis (XRD), nuclear magnetic resonance (1H NMR). IR spectra, UV-Vis and luminescence spectra of the products were recorded in the solid state. Following formulas of the obtained compounds were predicted: [Zn(I3P)2(2,2'-bipy)] (2,2'-bipy = 2,2'-bipyridine), [Zn(I3O)2(4,4'-bipy)], [Zn(I3P)2(4,4'-bipy)] (4,4'-bipy = 4,4'-bipyridine), [Zn(I3O)2(4-ampy)2]∙H2O (4 ampy = 4-aminopyridine), [Zn(I3P)2(bipyam)] (bipyam = 2,2'-dipyridylamine), [Zn(I3P)2(phen)] (phen = 1,10-phenanthroline), [Zn(I3P)2(neo)], [Zn(I3O)2(neo)] (neo = neocuproine).
