A new example of interpenetration that is simply controlled by modifying hydroxyl function in homochiral MOFs is reported. Interpenetrated and non-interpenetrated chiral metalâorganic frameworks (MOF-1 and MOF-2) were prepared by solvothermal reactions of [Cu(NO3)2]·3H2O in N,N-dimethylformamide (DMF)âH2O solution with (R)-2,2â²-dihydroxy-1,1â²-binaphthyl-5,5â²-dibenzoic acid (H2L1) and (R)-2,2â²-dimethoxy-1,1â²-binaphthyl-5,5â²-dibenzoic acid (H2L2), respectively. Interpenetrated chiral MOF-1 exhibited much higher catalytic performance in the DielsâAlder reaction of acrolein and 1,3-cyclohexadiene than non-interpenetrated chiral MOF-2.
报道了一个新的互穿实例,该实例可以通过修饰纯手性 MOF 中的羟基功能来简单地控制。通过 [Cu(NO3)2]·3H2O 在 N,N-二甲基甲酰胺 (DMF)·H2O 溶液中的溶剂热反应制备互穿和非互穿手性金属·有机骨架 (MOF-1 和 MOF-2)与 (R)-2,2-二羟基-1,1-二萘基-5,5-二苯甲酸 (H2L1) 和 (R)-2,2-二甲氧基-1,1-二分别为-联萘-5,5-二苯甲酸(H2L2)。互穿手性MOF-1在丙烯醛与1,3-环己二烯的Diels-Alder反应中表现出比非互穿手性MOF-2高得多的催化性能。
