A method of capturing water from a gaseous composition comprising water vapour (e.g., air), the method comprising:
(a) providing a metal-organic material; and
(b) contacting the metal-organic material with water and/or water vapour;
wherein upon contact with water and/or water vapour the material switches from a first state to a second state wherein the second state is able to retain a higher amount of water than the first state.

Dichromate (Cr2O72–) pillared pcu hybrid ultramicroporous materials, while previously shown to exhibit benchmark selectivity for small polarizable gases, sometimes suffer from poor stability when exposed to moisture, which could limit their potential application in gas separation systems. In attempting to improve their stability toward humidity, we have crystal engineered two new families of DICRO-L-M-i
重铬酸盐(Cr 2 O 7 2–)支柱的pcu杂化超微孔材料,虽然先前已显示出对小的可极化气体具有基准选择性,但有时暴露于湿气时稳定性较差,这可能限制了它们在气体分离系统中的潜在应用。在试图改善他们对湿度的稳定性,我们工程改造的晶体的两个新族DICRO-LMI式的物质[M(L)2(CR 2 ö 7)] Ñ(M =倪2+,钴2+ ; L = 5:1,4-双(4-吡啶基)二甲苯;6:1,4-双(4-吡啶基)二氢呋喃)。结合先前报道的类似物DICRO-4-Ni-i对这些材料进行评估,就其对湿气的稳定性而言,发现增加了二吡啶基有机连接基上甲基的数量与对湿气的稳定性之间的关系。

A method of capturing water from air, the method comprising:
(a) providing a two-dimensional layered material; and
(b) contacting the material with water and/or water vapour;
wherein upon contact with water and/or water vapour the material switches from a first state to a second state wherein the second state is able to retain a higher amount of water than the first state.
A method of capturing water from a gaseous composition comprising water vapour (suitably air), the method comprising: (a) providing a metal-organic material; and (b) contacting themetal-organic material with water and/or water vapour; wherein upon contact with water and/or water vapour the material switches from a first state to a second state wherein the second state is able to retain a higher amount of water than the first state.
