Specifications | MSDS | Literature and Reviews


3,3′′,5,5′′-tetrakis(4-carboxyphenyl)-p-terphenyl (H4TCPT), CAS number 1816997-25-7, is a linear terphenyl ligand with four side arms of 4-carboxyphenyl groups.

Highly stable MOFs, [Zr6O4(OH)8(HO)4(L)2 ] (BUT-14), where L is H4TCPT,  is highly porous with BET surface areas of 3,595 m2 g−1 , exhibiting excellent selective detection ability toward trace amounts of Fe3+ ion over other metal ions in  water system  in terms of distinct fluorescent quenching. with a detection limit of 212 ppb.

Chemically and hydrolytically stable chromium-based MOF Cr-soc-MOF-1 shows extraordinarily high porosity with a surface area of 4,549 m2/g with the ability to capture 200 wt % of water of its body weight over more than 100 adsorption-desorption cycles. Cr-soc-MOF-1 as an adsorbent find potential applications for water/moisture adsorption such as moisture control, dehumidification, adsorption-based desalination, and adsorption heating and cooling pumps.

Al-soc-MOF, another MOF platform  using H4TCPT ligand as the linkers and aluminium ion clusters as the nodes,  can address the challenging dual target of 0.5 g/g (gravimetric) and 264 cm3 (STP)/cm3 (volumetric) methane storage. Al-soc-MOF also exhibits the highest total gravimetric and volumetric uptake for carbon dioxide and oxygen at relatively high pressures among all microporous MOFs.
