Lambda-zirconium phosphate covalently pillared with 1,4-biphenyldicarboxylate: a new λ-type rigid microporous framework

A new layered pillared material [ZrPO4(OH)0.60(C14H8O4)0.20(CH3)2SO] based on λ-zirconium phosphate (λ-ZrP) and 1,4-biphenyldicarboxylic acid (bpdc) has been prepared. The synthesized material is characterized by X-ray diffractometry, FT-IR spectrophotometry, elemental, thermogravimetric and N2 adsorption/desorption analyses. The used analysis techniques reveal that the bpdc is successfully incorporated inside the interlayer region of λ-ZrP. Regarding the N2 adsorption/desorption analysis of λ-ZrP-bpdc, it gives a moderate specific area of 98 m2 g−1 and an average pore diameter of 0.88 nm. Therefore, a new λ-type rigid microporous framework is obtained. From the practical perspective, there would be a good potential for implementing applications of ZrPO4(OH)0.60(C14H8O4)0.20(CH3)2SO in the fields of inclusion chemistry, molecular shape recognition and heterogeneous catalysis.
