Due to the excellent ion-sensing potential of covalent organic frameworks (COFs), the new imine-linked conjugated COF (IC-COF) is synthesized through a water-based synthesis reaction between ...

SEM and energy-dispersive X-ray spectroscopy (EDS) mapping images were obtained using a focused ion beam scanning electron microscope (Helios 5 UC, FEI). Transmission electron microscopy (TEM) images ...
