Distinctly selective reactions of based on acetate lead(II) and hydrophilic 3-(4-carboxyphenoxy)phthalic acid

• In this system, the coordination ability of carboxylic O atom is stronger than N atom.
• Three hydrophilic carboxyl groups in H3L lead to the good solubility in water phase.
• The -O- motif in H3L makes two benzene ring rotate to adapt specific assembly ways.

Exceptional 3D Pb(II) MOFs constructed by Pb5(II) cluster motifs have been obtained by hydrothermal reaction of hydrophilic 3-(4-carboxyphenoxy)phthalic acid (H3L) and acetate lead in aqueous solution. Specifically, in this system, an obvious selective reaction of Pb(OAC)2 and H3L has been found. No matter the N-containing heterocyclic auxiliary ligands exist or not, the same products without auxiliary ligand are generated. Moreover, the luminescent property of 1 has also been investigated.
