Embodiments of the present disclosure describe carbocyclic pseudo Tröger's base (CTB) amines. Embodiments of the present disclosure further describe microporous polymers derived from pseudo CTB amines, including, but not limited to, polyimides, CTB ladder polymers, and network porous polymers. Other embodiments describe a method of separating chemical species in a fluid composition comprising contacting a microporous polymer membrane with a fluid composition including at least two chemical species, wherein the microporous polymer membrane includes one or more of a ladder polymer of intrinsic microporosity, a microporous polyimide, and a microporous network polymer; and capturing at least one of the chemical species from the fluid composition.
