2 . The composition of claim 1 , wherein n is 3 and m is 3, n is 2 and m is 3, n is 3 and m is 2, n is 4 and m is 2, or n is 2 and m is 4.

3 . The composition of claim 1 , wherein n is 3, m is 3, and the two dimensional polymer includes a structure

wherein each Z is an amide, urea, or carbamate linkage.

4 . The composition of claim 1 , wherein R 2 is H.

5 . A composition comprising a two dimensional polymer derived from one or more of the following planar building blocks:

wherein each R, independently is H, C1-C6 acyl or C1-C6 alkyl and each X is an amino group, hydroxyl group, carboxyl group, anhydride group, or isocyanate group, wherein the X groups, anhydride groups or carbonyl groups of the building blocks bond to a polyamine building block to form the two dimensional polymer.

6 . The composition of claim 5 , wherein the polyamine building block includes a planar amine including at least three amine groups each of which forms an amide bond with one of the planar building blocks to form the two dimensional polymer.
