通过将三蝶烯基组分熔融到联苯核上,制备了四种具有固有微孔性的有机分子(OMIMs)。由于它们的刚性分子结构不能有效地填充空间,这些OMIM形成具有显著微孔性的无定形材料,如通过在515-702 m2 g-1范围内的表观BET表面积所证明的。置于三蝶烯末端的大体积环状1′,2 ′,3 ′,4 ′-四氢-1 ′,1 ′,4 ′,4 ′-四甲基苯并单元在提高微孔性方面特别有效。
Four Organic Molecules of Intrinsic Microporosity (OMIMs) were prepared by fusing triptycene-based components to a biphenyl core. Due to their rigid molecular structures that cannot pack space efficiently, these OMIMs form amorphous materials with significant microporosity as demonstrated by apparent BET surface areas in the range of 515–702 m2 g–1. Bulky cyclic 1′,2′,3′,4′-tetrahydro-1′,1′,4′,4′-tetramethylbenzo units placed on the triptycene termini are especially efficient at enhancing microporosity.
