Specifications | MSDS | Literature and Reviews

1,1':4',1'':4'',1'''-quaterphenyl-3,3''',5,5'''-tetracarboxylic acid (H4QPTC), CAS number 921619-91-2, is a linear quarterphenyl with two carboxylic acid groups at 3,5-positions of each end benzene rings.

MOF with the chemical formula (NH₂(CH₃)₂[Zn₃(L)₂·3.5DMF]) (MOF-Zn-H4QPTC) (H4L = 1,1′,4′,1″,4″,1‴-quaterphenyl-3,5,3‴,5‴-tetracarboxylic acid) shows an unusual 4,8-connected 3D structure. The drug 5-fluorouracil (5-FU) uptake into the complex was about 22.5 wt.% per gram of dehydrated form of MOF-Zn-H4QPTC. 5-Fu is then released in a highly controlled and progressive fashion with 92% of the drug being released in 120 h.

Anionic MOF with In(III) centres and tetracarboxylic acid ligands (MOF-In-H4QPTC) shows kinetic trapping behaviour of hydrogen. With piperazinium dications in its pores, the framework exhibits hysteretic hydrogen adsorption.

Ratiometric thermometer encapsulating luminescent perylene dye into the pores of a europium metal–organic framework (MOF-Eu-H4QPTC), exhibits highly temperature dependent luminescence intensity ratio over the physiological temperature range, with a maximum sensitivity of 1.28% °C⁻¹ at 20 °C.
