分别以乙酸和吡啶为选择性调节剂，或仅以吡啶为选择性调节剂，合成了[Cu2(ndc)2(dabco)]n金属有机骨架（ndc = 1,4-萘二羧酸盐，dabco = 1,4-重氮杂环[2.2.2]辛烷）纳米立方和纳米片。这种方法可以调整晶体在不同方向上的生长，以实现由两种或两种以上类型的连接剂组成的金属有机框架（MOF）纳米晶体的尺寸和形状控制合成。与仅使用醋酸作为选择性调制剂制备的大块MOF材料或[Cu2(ndc)2(dabco)]n纳米棒相比，这些MOF纳米晶体具有较高的结晶度和更高的CO2吸收量，这可能是由于形貌对其气体吸附性能的影响。
Nanocubes and nanosheets of [Cu2(ndc)2(dabco)]n metal–organic framework (ndc = 1,4-naphthalene dicarboxylate; dabco = 1,4-diazabicyclo[2.2.2]octane) were synthesized by using simultaneously acetic acid and pyridine or only pyridine, respectively, as selective modulators. This approach can tailor crystal growing on different directions for the size- and shape-controlled synthesis of metal–organic framework (MOF) nanocrystals whose structure is composed of two or more types of linkers using selective modulators. These MOF nanocrystals exhibit high crystallinity and higher CO2 uptakes compared to that of the bulk MOF material or of the [Cu2(ndc)2(dabco)]n nanorods generated by using only acetic acid as the selective modulator, which may be due to the morphology effect on their gas sorption properties.
