Specifications | MSDS | Literature and Reviews

4',4''',4'''''-nitrilotris(([1,1'-biphenyl]-3,5-dicarboxylic acid)) (H6NBPD), CAS number 1347748-59-7, has a triphenylamine core centre with benzene-3,5-dicarboxylic acid anchoring groups attached to the 4-positions of the phenyl rings, the each end of triphenylamine core.

Metal–organic framework MFM-115a with copper node centres and 4',4''',4'''''-nitrilotris(([1,1'-biphenyl]-3,5-dicarboxylic acid)) as the ligand linkers, displays an exceptionally high deliverable CH₄ capacity of 208 v/v between 5 and 80 bar at room temperature, making it among the best performing MOFs for CH₄ storage.

Upon heating, an in situ solid phase transformation can be observed from hydrogen-bonded organic framework HOF-NBPD(DMA) (NBPD = H6NBPD, DMA=dimethylamine cation) to HOF-NBPD, accompanied with transformation of the electronegative skeleton into neutral one. As a result, the pore surface of HOF-NBPD has become nonpolar. Practical breakthrough experiments demonstrate HOF- NBPD could produce polymer-grade C₂H₄ from C₂H₆/C₂H₄ (1/99, v/v) mixture with a high productivity of 29.2 L kg⁻¹ at 298 K, which is about five times as high as HOF- NBPD (DMA) (5.4 L kg⁻¹).
