Metal Organic Frameworks (MOFs) Tetraphenylmethane Ligand

A rigid tetrahedral aromatic tecton ligand linker for MOFs in applications of chemisorption of iodine


Tetra(4-(4-pyridyl)phenyl)methane (TPPM), is a rigid tetrahedral aromatic tecton which can be considered as the decoration of tetraphenylmethane with four p-substituted pyridyl rings. TPPM can act as hydrogen bond acceptor with its four nitrogen atoms forming N···H bondings. Meanwhile, due to the the presence of aromatic rings, TPPM can also give rise to π···π and C-H···π interactions as weak hydrogen bond donor.

Thermally stable network [Cu4I4(PPh3)4]-L, where L is TPPM, uniquely adsorbs iodine (I2) by chemisorption through I3 formation. The chemisorbed I2 readily desorbs above 380 K owing to the dynamic motion of the framework.
