We report, for the first time, construction of a sulfur electrode in a lithium–sulfur battery by using covalent-organic frameworks (COFs) as a host.

Herein, we report the targeted synthesis and solid state assembly of a novel triazine-based [4+6] organic molecular cage. The tetrahedral cage features a large cavity (∼2070 Å(3)), and after desolvation, the resultant material exhibits a high Brunauer-Emmett-Teller surface area of 1181 m(2) g(-1) and also features selective adsorption of CO2 over N2.

Herein, we report the synthesis and postsynthetic modification of a novel alkyne-tagged zirconium metal-organic framework, UiO-68-alkyne. The alkynyl groups in the pore surface were subjected to a "click" reaction, achieving quantitative conversion and maintaining the crystallinity of the framework.
