Abstract (AI)
Three new thorium-based MOFs based on 1,2,4,5-tetrakis(4-carboxyphenyl)benzene (H4TCPB) were obtained under a similar reaction system (metal salt, ligand, solvent, and acid are the same). Th(iv) forms the central unit of the MOFs in mononuclear and binuclear clusters, respectively. All the MOFs show blue ligand-based luminescence under an ultraviolet environment. This is the first time that multiple thorium-based MOFs with luminescence have been found with the same ligand.
Key Findings
1
All synthesized MOFs exhibit blue ligand-based luminescence under ultraviolet irradiation.
2
The thorium(IV) centers in the MOFs assemble into both mononuclear and binuclear clusters as central structural units.
3
This work is the first report of multiple thorium-based luminescent MOFs constructed with the same ligand (H4TCPB).
4
Three new thorium-based metal–organic frameworks (MOFs) were synthesized using the ligand 1,2,4,5-tetrakis(4-carboxyphenyl)benzene (H4TCPB) under the same reaction conditions.
