Abstract

U okviru ovog diplomskog rada provedena je sinteza i karakterizacija novih porfirinskih iadamantanskih poroznih organskih polimera s azo poveznicama. Kao polazne građevne jedinke za sintezu azo polimera korišteni su tetranitro i tetraamino derivati s porfirinskom i/ili adamantanskom središnjom jedinicom. Azo polimeri pripravljeni su redukcijom tetranitro monomera, oksidacijom tetraamino monomera ili reakcijom kondenzacije tetranitro monomera i komercijalno dostupnih aromatskih diamino i triamino monomera u bazičnim uvjetima. Sintetizirani polimeri okarakterizirani su IR spektroskopijom, spektroskopijom NMR u čvrstom stanju, difrakcijom rendgenskog zračenja na polikristalnom uzorku, termogravimetrijskom analizom i mjerenjem adsorpcijsko-desorpcijskih izotermi dušika. Azo polimerima s velikom specifičnom površinom određen je i kapacitet vezanja ugljikovog dioksida (CO2) pomoću termogravimetrijske analize u struji CO2. Prikupljeni rezultati ukazuju da odabir metode sinteze i polaznih građevnih jedinki uvelike utječe na funkcionalna svojstva sintetiziranih azo polimera.

Abstract (english)

In this diploma thesis synthesis and characterization of new porphyrin and adamantane porous organic polymers with azo linkages were conducted. Tetranitro and tetraamino derivatives with porphyrin and/or adamantane central units were used as starting building blocks for the synthesis of azo polymers. Azo polymers were prepared by the reduction of tetranitro monomers, oxidation of tetraamino monomers, or condensation reactions between tetranitro monomers and commercially available aromatic diamine and triamine monomers under basic conditions. The synthesized polymers were characterized by IR spectroscopy, solid-state NMR spectroscopy, X-ray powder diffraction, thermogravimetric analysis, and nitrogen adsorption- desorption measurements. Azo polymers with high specific surface area were also evaluated for their carbon dioxide (CO2) binding capacity through thermogravimetric analysis in a CO2 stream. The collected results indicated that the choice of synthesis method and starting building blocks significantly influences the functional properties of the synthesized azo polymers.
