| Abstract: | A promising alternative strategy for designing mesoporous metal–organic frameworks (MOFs) has been proposed, by modifying the symmetry rather than expanding the length of organic linkers. By means of this approach, a unique MOF material based on the target Zn8(ad)4] (ad=adeninate) clusters and C3‐symmetric organic linkers can be obtained, with trigonal microporous (ca., 0.8 nm) and hexagonal mesoporous (ca., 3.0 nm) 1D channels. Moreover, the resulting 446‐MOF shows distinct reactivity to transition and lanthanide metal ions. Significantly, the transmetalation of CoII or NiII on the ZnII centers in 446‐MOF can enhance the sorption capacities of CO2 and CH4 (16–21 %), whereas the impregnation of EuIII and TbIII in the channels of 446‐MOF will result in adjustable light‐emitting behaviors. |
