Abstract

This project aims to synthesize and characterize novel metal-organic frameworks (MOFs) incorporating a Schiff base and an anthrazolinic derivative, in conjunction with rare earth metals such as yttrium and terbium. MOFs are highly porous crystalline materials whose properties can be tailored by selecting specific metal centers and organic ligands, rendering them highly promising for applications that demand thermal stability, controlled functionalization, and enhanced optical performance.The research will be conducted in collaboration with Concordia University, under the supervision of Professor Ashlee Howarth, an expert in the synthesis of rare-earth-based MOFs. Initially, the organic ligands will be synthesized in Brazil and subsequently sent abroad, where the metal-organic frameworks will be assembled and characterized. This study aims to investigate how variations in the organic ligands and the substitution of the central metal influence the structural organization, thermal stability, and photophysical properties of the MOFs, thereby expanding their potential applications.The characterization of the synthesized materials will be conducted using X-ray diffraction (XRD), UV-Vis spectroscopy, solid-state fluorescence spectroscopy, and comprehensive structural analyses of porosity and thermal stability. The data acquired from these investigations will contribute to a deeper understanding of the physicochemical behavior of these novel materials and their potential applicability in photopolymerization systems, gas storage, and other emerging technological fields.In addition to advancing knowledge on rare-earth-based MOFs, this research internship will facilitate the incorporation of novel synthetic approaches into the Brazilian research group, enabling future investigations in the field of advanced functional materials and strengthening collaborative efforts between the participating research teams.
