Abstract

U sklopu ovog diplomskog rada, provedena je sinteza i karakterizacija novog aromatskog tetranitrozo/azodioksidnog spoja i novih aromatskih azo kovalentnih organskih polimera. Aromatski tetranitrozo spoj sintetiziran je oksidacijom odgovarajućeg aromatskog tetraamino spoja i okarakteriziran spektroskopijom NMR u otopini. Aromatski azo polimeri priređeni su reakcijom kondenzacije aromatskih tetranitro i tetraamino spojeva odnosno tetranitro i odabranih diamino spojeva u bazičnim uvjetima.
Strukturne karakteristike i termička svojstva aromatskih azo polimera proučena su tehnikama IR spektroskopije, difrakcijom rendgenskog zračenja na polikristalnom uzorku i termogravimetrijskom analizom. Usporedba IR spektara te difraktograma polikristalnih uzoraka polaznih spojeva i dobivenih produkata ukazuje na nastanak amorfnih aromatskih azo polimera.

Abstract (english)

Within this diploma thesis, the synthesis and characterization of novel aromatic tetranitroso/azodioxide compound and azo covalent organic polymers was performed. The aromatic tetranitroso compound was synthesized by oxidation of the corresponding aromatic tetraamino compound and characterized by NMR spectroscopy in solution. Aromatic azo polymers were prepared by condensation reaction of aromatic tetranitro and tetraamino compounds, and tetranitro and selected diamino compounds under basic conditions.
The structural characteristics and thermal properties of aromatic azo polymers were studied by IR spectroscopy, X-ray powder diffraction and thermogravimetric analysis. Comparison of IR spectra and X-ray powder diffractograms of starting compounds and obtained products indicated formation of amorphous aromatic azo polymers.
