Metal-organic framework based on nickel, L-tryptophan and 1,2-bis(4-pyridyl)ethylene, consolidated on a track-etched membrane

O. Yu Ponomareva, Nikita A. Drozhzhin, И. И. Виноградов, Tatiana N. Vershinina et autres

An approach to the functionalization of track-etched membranes (TM) by metal-organic framework consisting of nickel, L-tryptophan, and 1,2-bis(4-pyridyl)ethylene (Ni-MOF) was developed. The effect of TM surface charge on the Ni-MOF self-assembly was studied. It was established that the microstructure of Ni-MOF does …
