“…Zulfiqar et al recently reported one of the few studies of amidoxime, presenting both theoretical and experimental work that demonstrated the potential of amidoxime for CO 2 separation [17]. Patel modified polymers of intrinsic microporosity with amidoxime and observed an increase in CO 2 adsorption capacity [18]. In our work, we grafted the amidoxime group onto the surface of porous carbon synthesized by a soft-templating method and measured CO 2 adsorption parameters.…”

“…Modifications to the nitrile substituents of PIM-1 to introduce carboxylic acid, thioamide, and tetrazole groups all significantly reduce the apparent surface area presumably due to the hydrogen bonding properties of these groups increasing polymer cohesion and improving packing [69,71,73]. However, the introduction of amidoxime substituents does not reduce significantly the apparent surface area and has thus been termed a "non-invasive" modification [72].…”

“…These include simple hydrolysis groups to provide carboxylic acids [69,70], reaction with P 2 S 5 to provide thioamines [71], reaction of hydroxylamine to give amidoximes [72], and the reaction of sodium nitride to provide tetrazole functionality (Scheme 2) [73].…”

This paper focuses on polymers that demonstrate microporosity without possessing a network of covalent bonds-the so-called polymers of intrinsic microporosity (PIM). PIMs combine solution processability and microporosity with structural diversity and have proven utility for making membranes and sensors. After a historical account of the development of PIMs, their synthesis is described along with a comprehensive review of the PIMs that have been prepared to date. The important methods of characterising intrinsic microporosity, such as gas absorption, are outlined and structure-property relationships explained. Finally, the applications of PIMs as sensors and membranes for gas and vapour separations, organic nanofiltration, and pervaporation are described.

“…Amidoximes are known to be CO 2 -philic [114], and functionalization of PIM-1 by amidoxime will create sites that have strong affinity toward CO 2 through its high quadruple moment. In 2012, Patel and Yavuz [115] synthesized the amidoxime-PIM-1 successfully through a conventional and non-invasive synthetic route (Fig. 5.14a, Reaction C).…”

Microporous organic polymers (MOPs) are a unique class of porous materials consisting solely of the light elements (C, H, O, N, etc.). A series of vivid characteristics of MOPs, such as high-specific surface area, good physicochemical stability, diverse pore dimensions, topologies, and chemical functionalities, make them suitable adsorbents for CO 2 capture. In this chapter, MOPs are categorized into four classes according to the types of organic reactions and the chemical structures of the resulting materials: hypercrosslinked polymers (HCPs), covalent organic frameworks (COFs), polymers of intrinsic microporosity (PIMs), and conjugated microporous polymers (CMPs). For each type of the polymer network, the state-of-the-art development in the design, synthesis, characterization, and the CO 2 sorption performance is reviewed. Strategies for controlling CO 2 uptake capacity and adsorption enthalpy via manipulation of surface area, pore size, and functionality are discussed in detail. These studies would open up many new possibilities for the development of the novel solid sorbents targeting the CO 2 capture process. It is expected that this chapter will not only summarize the main research activities in this field, but also find possible links between basic studies and practical applications.
