almost completely unexplored. Here, we investigate the melting and glass-forming behaviour of a range of organic cages, including both shape-persistent POCs formed by imine condensation, and reduced and synthetically post-modified amine POCs that are more flexible and lack shape-persistence. The organic cages exhibited melting and quenching of the resultant liquids provides molecular glasses. One of

A simple, one-step amidation reaction is used to produce a range of 12-arm organicbuildingblocks for supramolecular chemistry via the derivatization of porous imine cages. As an example, microporous dendrimers are prepared.

Porousorganiccages (POCs) were used as an additive to enhance the CO2 diffusion in flow cell catalyst layers, thus boosting the productivity of the CO2 electroreduction reaction. The Faradaic efficiency (FE) of C2+ products reached 76.1 % when Cu-nanorod/CC3 (one of the POCs) was used. The diffusion of CO2 through CC3 to the nanocatalyst surface is easier than in liquid electrolyte, therefore more
多孔有机笼 (POC) 用作添加剂以增强流通池催化剂层中的 CO 2扩散,从而提高 CO 2电还原反应的生产率。当使用 Cu-nanorod/CC3(POC 之一)时,C2+ 产品的法拉第效率 (FE) 达到 76.1%。CO 2通过CC3扩散到纳米催化剂表面比在液体电解质中更容易,因此更多的CO 2分子与纳米催化剂接触。

Porous materials (such as organic polyamine cage compounds) and methods of stabilising porous materials which are otherwise prone to pore-collapse are described. Such stabilisation is accomplished through the use of molecular ties to create bridges between reactive groups of a (potentially) porous material to thereby strengthen and stabilise the porous structure. The chemistry involved in, and the results of, the stabilisation of porous materials to provide a new sorption composition comprising the very materials which are generally prone to pore-collapse are also described.
