The porous metal organic framework material is very popular as an innovative functional material. The flexible tetra-carboxylic acid is one type of chelate ligand, barely used to construct metal-organic framework. The rigid di-carboxylic acid is one type of efficient ligand to construct transition metal-organic framework. However, both of the two acids are unable to meet the high coordination demand of rare earth, therefore, it is very difficult to construct a stable porous framework by using the two type of ligands alone. By using flexible tetra-carboxylic acid and rigid di-carboxylic acid, will some new porous and stable MOFs be prepared? Thank you for your review on this project.

Dear Masoud Mirzaei,
Thank you for your kind reply and suggestion. Thank you very much.
I know that the rigid di-carboxylic acids are one type of efficient ligands to construct porous MOFs with kinds of applications. When involving lanthanide metal ions, only few porous and stable MOFs were reported. In fact, I want to know whether the conbination of flexible tetra-carboxylic acid with rigid dicarboxylic acid may helpful to find more novel, porous and stable lanthanide MOFs.
Mr. Chen,
Generally functionalized - COOH containing organics are among the prominent templates for ligands
