| titleOfInvention | Polymers of intrinsic microporosity (pims) containing locked spirobisindane structures and methods of synthesis of pims polymers |
| abstract | A method of increasing the rigidity of PIM homo- or co-polymers including repeating units containing at least one biscatechol monomer having a fused spiro-bisindane (SBI) ring system of Formula (I), the SBI ring system including a bicyclic spiro-carbon: (I) wherein each R1 can be the same or different, each R2 can be the same or different and wherein R1 and/or R2 are selected from any one or more of H; straight or branched, saturated or unsaturated lower C1-C6 alkyl groups, wherein the lower alkyl groups can include aromatic or non-aromatic ring structures; R3OR4, R3O(C═O)R4, R3C(═O)OR4, or R3OH, wherein each of R3 and R4 are the same or different and are selected from straight or branched, saturated or unsaturated lower C1-C6 alkyl groups; and R5 and R represent suitable linking monomers, wherein the linking monomers can be the same or different and are preferably selected from any one or more tetrahalo aromatic monomers; and wherein the method includes the step of introducing an intra-molecular lock between C1 and C2 of the biscatechol monomer of Formula (I). |
