Covalent Organic Frameworks (COFs) Pyrene Ligand

An aldehyde functionalised bridging ligand linker for COFs in application of photocatalytic water splitting, gas uptake and energy storage


1,3,6,8-Tetrakis(4-formylphenyl)pyrene (TFPPY) tecton has a pyrene core with four side 4-formylphenyl functional groups which grows the structure via condensations reactions.

Constructed from 1,3,6,8-tetrakis(4-formylphenyl)pyrene and 4,4'-(5,6-dichlorobenzo[c][1,2,5]thiadiazole-4,7-diyl)dianiline as the building blocks, two-dimensional (2D) covalent organic framework, namely Py-ClTP-BT-COF, showed great solar-to-hydrogen energy conversion efficiency with photocatalytic H2 evolution rates of 177.50 μmol h−1 and a high apparent quantum efficiency (AQE) of 8.45%.

With the introduction of oxygen atoms into the framework to increase the number of photogenerated electrons, pyrene-based amide COF, TFPPy–DP, demonstrated photocatalytic reduction and removal of toxic uranyl under visible light with 82% removal percentage of 238 ppm uranyl at pH 3 in 2 h of irradiation.

Microporous carbon material, Py-PDT POP-600, obtained by the carbonization of Py-PDT POP with 6,6′-(1,4-phenylene)bis(1,3,5-triazine-2,4-diamine) (PDA-4NH2) and 1,3,6,8-tetrakis(4-formylphenyl)pyrene repeating units, showed  a high nitrogen content with high surface area of 314 m2 g−1, high pore volume, and good thermal stability. Py-PDT POP-600 demonstrated excellent performance in CO2 uptake of 2.7 mmol g−1 at 298 K and a high specific capacitance of 550 F g−1 at 0.5 A g−1.
