Abstract
A polymer composition comprising a covalent triazine framework having the following structure: wherein: each asterisk (*) in A units denotes a point of covalent bonding with an asterisk in B units, and each asterisk (*) in B units denotes a point of covalent bonding with an asterisk in A units; r is an integer of 1-3; R is a fluorinated hydrocarbon containing at least two aromatic rings and at least one ether linkage between aromatic rings; the composition includes a multiplicity of A units and multiplicity of B units; and a portion of the connection points are terminated by endcapping nitrile groups. Also described are methods for producing the polymer and a microporous carbon material produced by pyrolysis of the porous polymer membrane. Also described are methods for using the polymer and microporous carbon material for gas or liquid separation, filtration, or purification.
