Abstract
Predmet istraživanja je usmjeravajući učinak tekućine i fulerena u kontroliranoj mehanokemijskoj sintezi polimorfnih i kompozitnih faza cinkova imidazolata. Osim dosad poznatih faza cinkova imidazolata čije su strukture „preguste“ za apsorpciju fulerena, pripravljene su tri nove topologije kompozita cinkova imidazolata s fulerenom: C 70 @CHA- ZnIm 2 i C 60 @CHA-ZnIm 2 , C60 @X-ZnIm 2 i C 60 @T-ZnIm 2 . X i T faze su zasad nove i nepoznate topologije. Dobiveni spojevi su izučavani difrakcijom rentgenskih zraka na praškastim uzorcima, termogravimetrijom, infracrvenom spektroskopijom i elektronskom spinskom rezonancijom. Dok se CHA-ZnIm 2 i X-ZnIm 2 faza mogu pripraviti samo uz prisustvo fulerena, T-ZnIm 2 faza se može pripraviti i bez fulerena, ali manje količine enkapsuliranog fulerena dodatno stabiliziraju ovu nestabilnu fazu. Količina apsorbiranog fulerena ovisi o vrsti i količini dodanog fulerena (C 60 ili C70 ) i o tipu faze kompozita.
Abstract (english)
The subject of research is the directing effect of liquid and fullerene in the controlled mechanochemical synthesis of polymorphic and composite phases of zinc imidazolate. In addition to the previously known zinc imidazolate phases whose structures are “too dense” for fullerene absorption, the inclusion of fullerene in the structure stabilized three new topologies of zinc imidazolate composites: C70 @CHA-ZnIm 2 and C 60 @CHA-ZnIm 2 , C 60 @X-ZnIm 2 and C 60 @T-ZnIm 2 . X and T phases have a new unreported topology. The obtained compounds were studied by X-ray diffraction on powder samples, thermogravimetry, infrared spectroscopy and electronic paramagnetic resonance. While the CHA-ZnIm 2 and X-ZnIm 2 phases can only be prepared with the addition of fullerene, T-ZnIm 2 phase can be prepared without the presence of fullerenes, but small amounts of encapsulated fullerene additionally stabilize the otherwise unstable phase. The amount of fullerene absorbed depends on the type of fullerene (C 60 or C 70 ), the amount of added fullerene and the type of composite phase.
