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

Abstract

A new layered pillared material [ZrPO 4 (-OH) 0.60 (C 14 H 8 O 4 ) 0.20 (CH 3 ) 2 SO] based on k-zirconium phosphate (k-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 N 2 adsorption/ desorption analyses. The used analysis techniques reveal that the bpdc is successfully incorporated inside the interlayer region of k-ZrP. Regarding the N 2 adsorption/desorption analysis of k-ZrP-bpdc, it gives a moderate specific area of 98 m 2 g -1 and an average pore diameter of 0.88 nm. Therefore, a new k-type rigid microporous framework is obtained. From the practical perspective, there would be a good potential for implementing applications of ZrPO 4 (OH) 0.60 (C 14 H 8 O 4 ) 0.20 (CH 3 ) 2 SO in the fields of inclusion chemistry, molecular shape recognition and heterogeneous catalysis.Graphical abstract A new layered pillared material [ZrPO 4 (OH) 0.60 (C 14 H 8 O 4 ) 0.20 (CH 3 ) 2 SO] based on k-zirconium phosphate (k-ZrP) and 1,4-biphenyldicarboxylic acid (bpdc) has been prepared.
