Creation of multifunctional microchannels by coordination polymers

微孔化合物由于其独特的分离、吸附、多相催化等性质，其化学性质得到了广泛的研究。特别是，以天然气的储存和运输为目的，创造新型多孔材料作为吸附剂是最具吸引力的研究领域。合成了一种新型的三维配位聚合物[{[CuSiF6 (4,4'-bpy)2] 8H2O)}n]（4,4'-bpy= 4,4'-联吡啶）。该网络提供的通道沿c轴的尺寸为ca 8 Å * 8 Å，沿A和b轴的尺寸为ca 6 Å * 2a。用HK法表示的差分孔隙体积图显示，在约7.8处只有一个尖峰Å。在已知甲烷吸附量最高的5A沸石上进行了甲烷吸附实验。XRPD测量表明，当通道中没有任何客体分子时，网络被保留。

The chemistry of microporous compounds have been studied extensively due to unique properties such as separation, adsorption, heterogeneous catalysis, and so on. Especially, creation of novel porous materials as adsorbents is a most attractive research field for the purpose of storage and transport of natural gas. A novel 3-D coordination polymer, [{[CuSiF6 (4,4'-bpy)2] 8H2O)}n](4,4'-bpy= 4,4'-bipyridine) was synthesized and characterized. This network provides channels with dimensions of ca 8 Å * 8 Å along the c-axis and ca 6 Å * 2 A along the a- and b-axes. The differential pore volume plot, represented by the HK method, shows only one sharp peak at ca 7.8 Å. The methane adsorption experiment was also carried out on zeolite 5A, which has the highest known methane adsorption capacity. XRPD measurement shows that the network is retained in the absence of any guest molecules in the channels.
