Synthesis, structure and luminescence properties of two Cd(ii)/M(i) (M = K, Rb) interpenetrated heterometallic frameworks based on giant double-walled cages†
Abstract
Two isostructural heterometallic MOFs [Cd3M6(TDPAT)2(H2O)9]·0.75H2O·4DMF·2MeOH (1 M = K; 2 M = Rb) were synthesized via solvothermal reaction. MOFs 1 and 2 are 3D chiral frameworks constructed by interpenetration of two identical 3D cage nets, which feature a giant double-walled heterometallic cage M36Cd24(TDPAT)8@M54Cd24(TDPAT)8. The luminescence properties of 1 and 2 including the quantum yield and lifetime values were also investigated.
