First claim
Opening claim text (preview).
We claim: 1. A microporous polyimide comprising the following structure: wherein n is an integer, wherein each X is independently selected from the group consisting of H, a halogen, an alkyl group, an aryl group, and a heteroaryl group, wherein Y is a bivalent organic group selected from the group consisting of: wherein R is an alkyl group and each R 1 , and R 2 are independently selected from the group consisting of: H, a halogen, and an alkyl group, wherein when the bond is directed to the middle of a ring, this indicates that, optionally, 1 to 4 R 1 or R 2 groups are attached to the ring and each R 1 or R 2 group is independently selected. 2. The microporous polyimide of claim 1 , wherein the microporous polyimide is selected from the group consisting of: 3. The microporous polyimide of claim 1 , wherein the microporous polyimide has a BET surface area of at least 100 m 2 /g. 4. The microporous polyimide of claim 1 , wherein the microporous polyimide has a BET surface area of about 100 m 2 /g to 1000 m 2 /g. 5. The microporous polyimide of claim 1 , wherein Y is SBI. 6. The microporous polyimide of claim 1 , wherein Y is SBF. 7. The microporous polyimide of claim 1 , wherein Y is BIN. 8. The microporous polyimide of claim 1 , wherein Y is TP. 9. The microporous polyimide of claim 1 , wherein Y is TB. 10. The microporous polyimide of claim 1 , wherein the microporous polyimide forms a membrane for performing gas separations, wherein the membrane-based gas separations include separations of gases selected from the group consisting of: O 2 /N 2 gas separations; H 2 /N 2 gas separations; H 2 /C 1+ hydrocarbons gas separations; He/C 1+ hydrocarbons gas separations; CO 2 /C 1+ hydrocarbons gas separations; CO 2 /N 2 gas separations; and olefins/paraffins gas separations.
