Polymers of intrinsic microporosity

Polymers of intrinsic microporosity (PIMs) consist of phthalocyanines and porphyrins containing metal ions or H in the cavities and they exhibit variation in surfaee area due to the varying metal ions or On tuning [Pg.214]

Fig ure 9.2 Representation of two ideal fragments of the network of Trip(Et)-PIM, showing how the shape of each macromolecule, as dictated by the architecture of the triptycene (Trip) units, prevents close intermolecular interactions between the planar struts . The loose network that arises from the ideal layered structure may account for the tendency of the materials to swell in organic solvents or during nitrogen adsorption, as indicated by the arrows, especially when bridgehead alkyl chains block interpenetration of the nitrile groups. [Pg.216]

Exploiting the design principle of PIMs, polyimide derivatives of PIMs (PIM-PIs) can be obtained with gas separation properties better than conventional polyimides with permeation properties. Permeation of PIM-PIs depends on the specific structure of the diamine units, variation of which empowers prediction of permeation parameters for other PIM-PI structures.  [Pg.217]

In addition, the polymers of intrinsic microporosity (PIMs), such as phthalocyanine networks and the Co phthalocyanine network-PIM (CoPc20), display high specific surface area, as confirmed by the N2 adsorption isotherm at 77 K, and by the adsorption of small organic probe molecules from aqueous solutions at 298 K [236], This material is basically microporous with an increased concentration of effective nanopores. [Pg.330]

The polymers of intrinsic microporosity (PIMs). These are rigid macromolecules composed of a fused-ring subunit which cannot pack space efficiently and hence form microporous materials (Figure 2.5) [68]. [Pg.48]

The inventors caU this polymer class polymers of intrinsic microporosity (PIMs) , because their porosity arises as a consequence of the molecular structure and is not generated solely through processing. The PIMs can exhibit analogous behavior to that of conventional materials, but, in addition, may be processed into convenient forms for use as membranes [291]. The gas-permeation properties of membranes formed from PIM-1 were investigated at the GKSS... [Pg.61]

If the answer to both these questions is yes , then the polymer can be said to have intrinsic microporosity [3,4] intrinsic because it is a consequence of the molecular structure and microporosity because we are dealing with micropores in the sense defined by lUPAC [2], This chapter introduces a concept for creating just such polymer structures, outlines the properties of the archetypal polymer of intrinsic microporosity , PIM-1, and describes recent results for PIM-1 obtained in the course of a European collaborative research project [5]. [Pg.30]
