New Covalent Organic Frameworks with Precise Control

New Covalent Organic Frameworks with Precise Control

covalent organic frameworks (COFs), were discovered in 2005, but their quality has been poor and preparation methods are uncontrolled. Now a Northwestern University research team is the first to produce high-quality versions of these materials, demonstrate their superior properties and control their growth. The researchers developed a two-step growth process that produces organic polymers with crystalline, two-dimensional structures.
