Two similar molecular building blocks, which both contain a hydrogen-bonded nitro group, have been prepared and crystallised. One structure has more flexibility with a butyl side chain which allows an open framework organic zeolite to form with large 10 Å diameter pores, whereas the other structure has less flexibility with an aryl side chain and is close packed. The pore size is comparable with those of the aluminophosphate VPI-5 (12 Å). It is concluded that some flexibility in the design of the building block for porous organic molecular materials was beneficial.
已经制备并结晶出两种相似的分子构建单元，它们都含有一个氢键连接的硝基。一种结构具有更大的灵活性，带有丁基侧链，这使得可以形成具有10埃直径大孔的开放骨架有机沸石，而另一种结构带有芳基侧链，灵活性较小，是紧密堆积的。其孔径与磷酸铝VPI-5（12埃）的孔径相当。得出的结论是，多孔有机分子材料构建单元设计中的一定灵活性是有益的。
