Embodiment

[0143] All starting materials and solvents were obtained from Aldrich Chemical Company and used without further purification unless otherwise stated. Tetrahydrofuran (HPLC grade, Aldrich) was passed through a PureSolv MD 7 solvent purification system before use. 4,4'-(1,10-phenanthroline-2,9-diyl)benzaldehyde was synthesized according to the published literature. All reactions were performed under ambient laboratory conditions, and unless otherwise stated, no precautions were taken to exclude atmospheric moisture. Loaded with reagents and filled with liquid N 2 The snap-frozen pyrex glass tube is evacuated using Schlenk tubing by fitting the open end of the tube inside a short length of standard rubber hose which is further secured to a ground glass faucet when the desired internal pressure is reached , the glass tap can be closed to isolate the assembly from the dynamic vacuum. Seal the tube at the desired static vacuum using an oxygen propane torch.

Abstract

The disclosure provides for covalent organic frameworks (COFs) that constructed from weaving a plurality of long organic threads together. In particular, the disclosure provides for the construction of woven COFS, where long organic strands are connected together in a woven pattern using organic ligands / complexes that when orientated in certain geometries are capable of reversibly binding metal ions.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to Provisional Application Serial No. 62 / 260,458, filed November 27, 2015, the disclosure of which is incorporated herein by reference. [0003] Statement Regarding Federally Funded Research [0004] This invention was made with United States Government support under Grant No. DE-SC0001015 awarded by the U.S. Department of Energy and Grant No. HDTRA1-12-1-0053 awarded by the U.S. Department of Defense. The US Government has certain rights in this invention. technical field [0005] The present disclosure provides covalent organic frameworks (COFs) constructed by weaving together multiple long organic wires. In particular, the present disclosure provides the construction of braided COFs in which long organic chains are linked together in a braided pattern using organic ligands / complexes that, when oriented in certain geometries, enable Reversibly binds metal ions. ...
