我们报道了一种合成材料[Co-2(bipy)(3)(SO4)(2)(H2O)(2)](bipy)(CH3OH),（1，其中bipy = 4,4'-联吡啶基），它包含离散的反应性和惰性结构基序，可以进行可逆取代反应，包括在反应位点协调和空间控制地引入联吡啶和甲醇分子。该反应定义了所得到的开放框架结构的孔隙几何形状，并控制了该结构吸收小分子的方式。在与金属中心结合的过程中，参与反应的分子通过一系列明确定义的相互作用来定位。
We report a synthetic material, [Co-2(bipy)(3)(SO4)(2)(H2O)(2)](bipy)(CH3OH), ( 1, where bipy = 4,4'-bipyridyl) that contains discrete reactive and inert structural motifs that undergo a reversible substitution reaction involving the concerted and spatially controlled introduction of bipyridine and methanol molecules at the reactive sites. This reaction defines the pore geometry of the resulting open-framework structure and controls the manner in which this structure sorbs small molecules. The molecules involved in the reaction are positioned by an array of well-defined interactions during their path to binding to the metal centers.
