本文从同一反应体系出发，在不同温度下合成了两种三维阴离子金属有机骨架：[(CH3CH2)(2)NH2]中心点[Zn(BTC)(1/3)(PYC)]中心点1/2CH(3)CN中心点2H(2)O(NKU-102)和[(CH3CH2)(2)NH2]中心点[Zn-2(BTC)(PYC)]中心点1.5h(2)O中心点DEF(NKU-103)。虽然两者都是阴离子骨架，但NKU-102具有基于八面体笼形的封闭三维骨架，对有机染料的吸附能力可以忽略不计，而NKU-103具有开放的三角形微通道，周围环绕着两种螺旋链，因此对小分子阳离子有机染料表现出良好的尺寸选择性吸附。
In this paper, two 3D anionic metal-organic frameworks, [(CH3CH2)(2)NH2]center dot[Zn(BTC)(1/3)(PyC)]center dot 1/2CH(3)CN center dot 2H(2)O (NKU-102) and [(CH3CH2)(2)NH2]center dot[Zn-2(BTC) (PyC)]center dot 1.5H(2)O center dot DEF (NKU-103), were constructed from the same reaction system at different temperature. Though both are of anionic framework, NKU-102 possesses a sealed 3D framework based on octahedral cage and shows negligible adsorption capacity of organic dyes, whereas NKU-103 features an open triangular microchannel surrounded by two types of helical chains, and thus exhibits outstanding size-selective adsorption toward small cationic organic dyes.
