Cross-linked polymeric resins from anilines linked together with dithiocarbamate alkyl chains. A process for producing the cross-linked polymeric resins by Mannich-type polycondensation of anilines and diaminoalkanes linked together by an aldehyde and subsequent conversion of one or more amine functionalities to dithiocarbamate moieties. In addition, a method for removing heavy metals, such as Hg(II) from aqueous solution via contacting and treatment with the cross-linked polymeric resins.

The present invention relates generally to substrates for making polymers and methods for making polymers. The present invention also relates generally to polymers and devices comprising the same.

The present invention relates to, in general, methods of fabricating a covalent organic framework (COF) and the COF thereof. In particular, the method comprises forming an acylhydrazone bond with an optionally substituted 2-alkoxybenzohydrazidyl moiety. The resultant COF has an x-ray diffraction 2-theta peak at about 3° with a full width half maximum (FWHM) of about 0.2° to about 0.4°.

The present invention relates to a method for preparing a covalent organic framework (COF) materials—a reversible polycondensation/termination method, the COF materials prepared by the method have high crystallinity, high specific surface area, regular and controllable morphology. The present invention also relates to a method for repairing defects of COF materials—reversible degradation-recombination, the method can eliminate defects of existing COF materials, thereby increasing the crystallinity and specific surface area of COF materials and improving their morphological characteristics.
