  • ADDITIVE MANUFACTURING OF LARGE-AREA COVALENT ORGANIC FRAMEWORK THIN FILMS
    Publication number: 20230241642
    Abstract: Systems and methods for preparing covalent organic framework (COF) thin films is disclosed herein. The systems and method utilize COF colloidal inks, having a diameter of 10-1000 nm, expelled through a nozzle onto a substrate to prepare the COF thin film. The plurality of COF colloidal ink droplets have an effective deposition diameter from the nozzle onto a masked or unmasked substrate, where the substrate may be heated to an effective COF deposition temperature.

  • TAUTOMERIC SENSING USING A COVALENT ORGANIC FRAMEWORK
    Publication number: 20220341851
    Abstract: Disclosed herein are sensors comprising a covalent organic framework (COF). The COF comprising a tautomerically active subunits (TAS) capable of reversible iminol-to-ketoenamine tautomerism between a first tautomer and a second tautomer and a inking group. Methods of detecting analytes with the sensors are also disclosed.
