Diversely shaped porous coordination polymer particles (CPPs) were synthesized by a simple solvothermal reaction of 1,4-benzenedicarboxylic acid (H2BDC) and In(NO3)3 x xH2O in DMF. The growth of crystalline CPPs was controlled through a particle growth blocking event involving blocking agent interaction with particular facets of CPPs and simultaneous particle growth interruption in a specific direction. Systematic reactions in the presence of various amounts of pyridine as a blocking agent were conducted to see the controlled CPP formation. Long rod, short rod, lump, and disk-shaped CPPs with hexagonal faces resulted in the presence of none, 1 equiv, 2 equiv, and 25 equiv of pyridine, respectively. The ultimate particle shape produced depends upon the amount of blocking agents used.
通过1,4-苯二甲酸(H2BDC)与硝酸铟(In(NO3)3·xH2O)在N,N-二甲基甲酰胺(DMF)中进行简单的溶剂热反应,合成了形状各异的多孔配位聚合物颗粒(CPPs)。通过颗粒生长阻断事件来控制结晶CPPs的生长,该事件涉及阻断剂与CPPs特定晶面的相互作用以及同时在特定方向上中断颗粒生长。在存在不同量吡啶作为阻断剂的情况下进行了系统反应,以观察可控的CPP形成。分别在不存在吡啶、1当量、2当量和25当量吡啶的情况下,得到了具有六边形面的长棒状、短棒状、块状和盘状CPPs。最终产生的颗粒形状取决于所用阻断剂的量。
