The goal of this research is to design and syntheses of hybrid cage polyhedral oligomeric silsesquioxane macromolecules and 2D-/3D-porous structures.
Juan Vivero-Escoto (CHEM)
The “bottom-up” modular construction of nanomaterials with molecular precision at the nanometer scale is of paramount interest for the fine-tuned control of their macroscopic properties. For this endeavor, it is essential to have ready and scalable access to a set of structurally well-defined, homogeneous nano-building-blocks (NBBs) with diverse functionalities. This project focuses on the rational design of novel hybrid materials by combining the well-established methodologies for the synthesis and functionalization of novel hybrid cage polyhedral oligomeric silsesquioxane (POSS) compounds with recent developments in the synthesis of porous frameworks such as covalent organic frameworks (COFs). The specific aims of this project are: 1) synthesize and characterize hybrid POSS macromolecules; 2) synthesize and characterize 2D- and 3D- hybrid POSS porous structures; and 3) study the self-assembly of cPOSS macromolecules.
REU Students’ Role
The student(s) in Dr. Vivero-Escoto’s lab will be involved with the synthesis and characterization of POSS compounds. These new molecules will be characterized using nuclear magnetic resonance, absorbance spectroscopies, and spectrometric methods. The student(s) will also participate in the fabrication and characterization of the 2D- and 3D- hybrid POSS porous structures. These materials will be characterized using N2 isotherms for surface area and pore size analysis, scanning electron microscopy and powder X-ray diffraction.
