Covalent organic frameworks (COF) are porous 2- or 3- dimensional polymer structures designed using only organic elements (C, O, N, B) that are constructed of the same repeating covalent bonding. They are used for gas storage, catalysts, chemical gas sensing, biomolecule capture, and optoelectronics. Our goal is construction of a COF from anthrone by nitration, oxidation to the anthraquinone, reductive coupling to form the tetranitrated bianthryl derivative, and reduction of the tetranitrated compound to a tetraamino compound. This symmetric tetraamino compound will be condensed with 1,4-dibenzaldehyde to generate a new COF, constructed of imine linkages. The structure is geometrically and energetically designed to possess electron- trapping characteristics in a 3-dimensional organic framework because the anthryl units will be arrested in an orthogonal orientation. We will accomplish the bulk of our synthesis and characterization at Millersville University and will carry out advanced characterization studies in the form of Differential Scanning Calorimetry (DSC), IR Spectroscopy, and UV-Visible Spectroscopy at Millersville University. We will also carry out Powder X-Ray Diffraction (PXRD), Thermal Analysis, and Gas Adsorption Analysis with our collaborators at James Madison University.
