A trigonal nanosized carboxylate ligand, 1,3,5-tris[4‘-carboxy(1,1‘-biphenyl-4-yl)]benzene (TCBPB), has been synthesized and applied
in the construction of porous metal−organic frameworks (MOFs).
A solvothermal reaction of TCBPB and a zinc salt in the presence
of pyridine produces <b>1</b>, an unstable MOF consisting of a tetrazinc
secondary building unit (SBU) with labile terminal ligands. Changing
pyridine to a noncoordinating base in the assembly procedure
affords <b>2</b>, a stable MOF with permanent porosity containing an
octazinc SBU without labile terminal ligands.
