Specifications | MSDS | Literature and Reviews

Tetrakis(4-formylphenyl)silane (TFPSi), CAS number 1055999-34-2, is a tectonic molecule with four 4-formylphenyl groups joined by a silicon centre. It has been predominantly used in development of metal-organic frameworks (MOFs) and coordination polymers (CPs).

Prepared by the bottom-up approach from TFPSi as one of the building blocks, 3D thioether-based COF JUC-570 demonstrated fast and high Hg²⁺ uptakes of 972 mg g⁻¹ at pH = 5. It is believed that the isopropyl groups around the imine bonds greatly improved its chemical stability by effectively maintaining the pore shape and size, endowing a high Hg²⁺ adsorption capacity (619 mg g⁻¹) and excellent cycle performance even at pH = 1.

MALP-2, also prepared from TFPSi, shows a largest adsorbed amount of 18.6 wt % CO₂ (273 K, 1 bar), and high adsorption selectivity of CO₂over N₂ (22.5) and over CH₄ (6.3). MALP-2 also demonstrated an excellent iodine vapor adsorption capacity (218.5 wt %) and remarkable solution iodine adsorption ability. The high chemical and physical stability, and excellent adsorption performances toward CO₂, toxic organic vapor, and iodine show that MALP COFs are promising candidates for environmental protection.
