1
and
3
, the use of the simple and short bmps ligands favours the assembly of discrete and/or low-dimensional metal-organic moieties, and the POMs are utilised as building units to complete the construction of the whole structures. For
2
and
4
, the large bpbb ligands facilitate the formation of porous metal-organic networks, in which the POMs are utilised as templates.
Two tetrazole-functionalized flexible ligands, bmps and bpbb, have been designed and used for the role-control of Keggin-type POMs in hybrid frameworks during self-assembly processes. |
