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.
