Abstract

Polymers represent a class of materials that are widely used in our daily lives. Despite its extreme importance, the polymerization reaction depends on the use of several reagents and toxic solvents, inert reaction conditions, heating and long reaction times. With this in mind, the photopolymerization reaction comes as an alternative to traditional methods of obtaining polymers, not requiring organic solvents, having a low energetic cost and short reaction time even at room temperature, being based on the application of light that triggers the reaction between monomers, forming the polymers. In this reaction, two components are necessary: a photoinitiator, which will initiate the polymerization reaction, and a monomer, which will form the polymer; it is also possible to use a coinitiator, which has the function of accelerating the reaction process. This project aims to synthesize and investigate the application of MOFs, a class of crystalline materials that has been extensively studied in several lines of research due to their unique physicochemical properties, as potential photoinitiating agents, especially MOFs based on a derivative quinoline. The main investigation of the project will be the synthesis of quinoline MOFs with different metal centers applied as photoinitiators in polymerization reactions for application in dental implants, using UDMA and TEG-DMA as monomers. Both photoinitiators and obtained polymers will be chemically and physically characterized by the following techniques: 1H-NMR, 13C-NMR, IR, UV-Vis, MS, TRF, EPR, XPS, SEM, AFM, TGA, BET, MIR, TG- DTA, DTG, DSC.
