Abstract
U okviru ovog diplomskog rada provedena je sinteza i karakterizacija 2,4,6-tris(4-nitrofenil)- 1,3,5-triazina i azo-premoštenih kovalentnih organskih polimera sa središnjom triazinskom jedinicom. Azo kovalentni organski polimeri priređeni su reakcijom navedenog trinitro derivata triazina i različitih diamino spojeva te melamina u bazičnom mediju. U svrhu strukturne i termičke karakterizacije korištene su različite tehnike poput IR spektroskopije, difrakcije rendgenskog zračenja na polikristalnom uzorku, termogravimetrijska analiza u sprezi s IR spektroskopijom (TG-IR) te spektroskopija NMR u čvrstom stanju. Usporedba IR spektara i difraktograma polikristalnih uzoraka polaznih spojeva i izoliranih produkata, te rezultati spektroskopije NMR u čvrstom stanju ukazuju na nastanak aromatskih azo kovalentnih organskih polimera amorfne građe. Rezultati TG-IR analize pokazuju visoku termičku stabilnost priređenih aromatskih azo kovalentnih organskih polimera. Također, identificirani su plinoviti produkti koji nastaju prilikom termičke razgradnje azo polimera.
Abstract (english)
In this diploma thesis synthesis and characterization of 2,4,6-tris(4-nitrophenyl)-1,3,5-triazine and azo-bridged covalent organic polymers with triazine central unit was performed. Azo covalent organic polymers were prepared by reaction of the specified trinitro triazine derivative and various aromatic diamino compounds and melamine in basic medium. For the purpose of structural and thermal characterization, various techniques such as IR spectroscopy, X-ray powder diffraction, thermogravimetric analysis hyphenated with IR spectroscopy (TG-IR) and solid state NMR spectroscopy were used. Comparison of IR spectra and diffractograms of starting compounds and isolated products as well as results of solid state NMR spectroscopy indicate the formation of amorphous aromatic azo covalent organic polymers. Results of TG-IR analysis show high termal stability of the prepared polymers. Gaseous products resulting from thermal decomposition of azo polymers have also been identified.
