New copper aryl phosphonates with auxiliary nitrogen ligands

Five New Coordination Polymers with a Bifunctional Phosphonate‐Sulfonate Linker Molecule

“…acids [7][8][9][10][11][12][13][14][15][16][17][18] or rigid m-or p-phosphonobenzenesulfonic acid. [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] First studies on 2-phosphonoethanesulfonic and 4-phosphonobutanesulfonic acids were carried out in the group of Alberti et al [7] Subsequently, high-throughput investigations allowed to identify fields of product formation and to establish synthesis-structure relationships of a variety of new CPs. [9][10][11][12][13][14]16,17] In addition, in situ X-ray diffraction studies were carried out to study the crystallization process in detail.…”

“…These compounds can be of great interest, particularly in the field of proton conduction, since due to the presence of mobile protons in the form of hydrogenphosphonate groups and water molecules in the crystal structure, defined proton conduction paths can be formed . However, there are only a few examples of CPs containing simultaneously sulfonate and phosphonate functions on the same linker molecule . The majority of such CPs have been obtained using flexible phosphonoalkylsulfonic acids or rigid m ‐ or p ‐phosphonobenzenesulfonic acid .…”

“…These CPs were mostly investigated for their structural features and spectroscopic characteristics. p ‐Phosphonobenzenesulfonic acid was successfully employed in the synthesis of Cu 2+ ‐,, , Ti 4+ ‐, and Zr 4+ ‐containing CPs.…”
