Metal-Organic Frameworks (MOFs): modulated synthesis and applications in catalysis, photonic and controlled release systems

Abstract

Metal-Organic Frameworks (MOFs) are a special class of coordinating polymers formed by the interaction between metal ions or clusters and multitopic organic linkers. The great interest in these materials are related to properties such as high crystallinity, permanent microporosity, high surface area values, low density and high thermal and chemical stability (in some cases). Within this perspective, these materials have been investigated for application in several areas such as gas storage and separation, heterogeneous catalysis, drug delivery, photonics, among others. Multiple synthetic routes for the preparation of MOFs have been used, including modulated synthesis, which refers to the use of functionalizing agents and/or coordinating modulators for the construction of MOFs with controlled size, shape and chemical functionality. These parameters may be decisive according to the type of application. Within this context, the main objective of this project is to prepare a series of transition metal and lanthanide ion-based MOFs with potential application in the areas of heterogeneous catalysis, specifically CO2 chemical transformation, photonics, contributing to the development of alternative light-emissive systems and biomedicine, including the study of complex substance (drugs, hormones and enzymes) release systems such as spherical nanocapsules and core-shell structures from MOF/MOF or MOF/layered double hydroxide systems.
