Abstract

Provedena je sinteza i karakterizacija aromatskih trinitro derivata benzena i piridina te novih aromatskih azo kovalentnih organskih polimera. Aromatski azo polimeri su pripravljeni kondenzacijom aromatskih trinitro derivata i različitih aromatskih diamino spojeva u bazičnom mediju. Pripravljeni spojevi su strukturno i termički okarakterizirani IR spektroskopijom, difrakcijom rendgenskog zračenja na polikristalnom uzorku i termogravimetrijskom analizom u sprezi s IR spektroskopijom (TG-IR). Usporedba IR spektara i difraktograma polikristalnih uzoraka polaznih spojeva i dobivenih produkata ukazuje na nastanak amorfnih aromatskih azo kovalentnih organskih polimera. Spregnutom tehnikom TG-IR utvrđena je visoka termička stabilnost sintetiziranih azo polimera te su identificirani plinoviti produkti koji se oslobađaju tijekom njihovog raspada.

Abstract (english)

Synthesis and characterization of benzene and pyridine aromatic trinitro derivatives and novel aromatic azo covalent organic polymers was performed. Aromatic azo polymers were prepared by condensation of aromatic trinitro derivatives and various aromatic diamino compounds in basic medium. The prepared compounds were structurally and termally characterized by IR spectroscopy, X-ray powder diffraction and thermogravimetric analysis hyphenated with IR spectroscopy (TG-IR). Comparison of IR spectra and diffractograms of starting compounds and obtained products indicated the formation of armorphous aromatic azo covalent organic polymers. High thermal stability of prepared azo polymers was confirmed and the gaseous products released during their decomposition were identified by means of TG-IR hyphenation.
