Abstract
A composition of matter including a two-dimensional covalent organic imidazole framework (COF) polymer having an aromatic backbone and ordered nanometer sized pores that may be functionalized with a variety of functional groups. A filtration membrane having both high throughput and highly selective transport or rejection of a species of interest based on size, charge or other molecular properties is readily formed of the two-dimensional COF polymer. The filtration membrane being formed by providing a substrate, such as anodic aluminum oxide (AAO), and then depositing exfoliated carboxyl COF onto the substrate.
