1. A two-dimensional (2D) polymer comprising:
a regular, repeating, 2D covalent bond network of (i) a plurality of identical nodes in two dimensions, each node comprised of one or more carbon-containing cyclic nodal units, which are joined by (ii) three or more identical linear bridge units, wherein the bridge units comprise: (a) polyethylene; (b) amide or polyamide comprising a nitrogen atom which directly bonds to a cyclic ring of a carbon-containing cyclic nodal unit; (c) thiazole or polythiazole, or imidazole or polyimidazole; (d) hydroquinone-diimidazopyridine or poly(hydroquinone-diimidazopyridine); (e) a monomer or polymer comprising 4-hydroxybenzoic acid and/or 6-hydroxy-2-naphthoic acid; (f) a monomer or polymer comprising one or more cyclic units and one or more esters; or (g) amic or polyamic acid.
