1. A method of producing a two-dimensional (2D) polymer film comprising:
(a) providing one or more first monomers comprising three or more reactive groups per molecule;
(b) providing one or more second monomers comprising two or more reactive groups per molecule;
(c) dissolving or dispersing the first and second monomers in a solvent;
(d) reacting the first and second monomers to form 2D bond network;
(e) removing the solvent,
wherein the first and second monomers are selected so as to form 2D polymer comprising:
a regular, repeating, 2D bond network of (i) a plurality of nodes comprised one or more nodal units which are joined by (ii) one or more linear polymer bridge units, wherein:
(vii) the bridge units are between 0.1-100 nm long;
(viii) each node is bonded to 3 or more bridge units;
(ix) the bridge units maintain the overall planarity of the 2D polymer, wherein the majority of bonds of the bridge units and their adjacent nodal units are located within a limiting distance measured perpendicularly from a single plane upon which the molecule substantially lies corresponding to three times the length of a carbon-carbon single bond; and
(x) the polymer comprises a single molecule having a length greater than 50 nm in both lateral in-plane dimensions.
