Secondary and tertiary amine-containing metal–organic frameworks (MOFs) have been synthesized, and unprecedented C–N bond cleavage phenomena were observed during MOF formation. Utilizing the secondary amine-containing ligand (BDC-NHMe), three new MOFs have been prepared, two of which are zinc(II)-based, IRMOF-NHMe (IRMOF = isoreticular MOF) and DMOF-1-NHMe (DMOF = dabco MOF), in addition to the zirconium(IV)-based
已经合成了含仲胺和叔胺的金属有机骨架(MOF),并且在MOF形成过程中观察到了前所未有的C–N键断裂现象。利用含仲胺的配体(BDC-NHMe),制备了三个新的MOF,其中两个是基于锌(II)的IRMOF-NHMe(IRMOF =等网状MOF)和DMOF-1-NHMe(DMOF = dabco MOF),以及基于锆(IV)的UiO-66-NHMe(UiO =奥斯陆大学)。在IRMOF和UiO-66合成条件下,将含叔胺的配体(BDC-NMe 2)转化为含仲胺的配体(BDC-NHMe),表明它是原位的MOF形成过程中配体的C–N键断裂。相反,含叔胺的DMOF-1-NMe 2已成功合成并用于CO 2吸附实验。
