摘要： A new class of ordered functional nanoporous material (OFNMs) with a unique combination of electronic conductivity, gas transport ability, and ion transport properties are provided. The OFNM provided is highly ordered and contains nanometer scale pores lined with nitrogen atoms. The pores have dimensions of from 1.2 nm to 82 nm of longest linear extent across the pore. The functionality within the pore is controlled through selection of groups that extend into the pore. The degree of conjugated aromaticity is readily controlled to adjust the electrical conductivity properties of the resulting structure. By adjusting the groups external to the pore, three-dimensional structures are formed that are organic mimics of zeolites, metal organic frameworks (MOF), or perovskites.

摘要： 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.
