Polymers of intrinsic microporosity (PIMs) in sensing and in electroanalysis

Effects of g-C3N4 Heterogenization into Intrinsically Microporous Polymers on the Photocatalytic Generation of Hydrogen Peroxide

“…This leads to good solvent processability (due to molecular interactions in the solid being weak 47 ), and uniformly microporous film deposits cast from solution with typically 1 nm diameter pores. 48 Applications for PIMs have emerged in gas permeation and separation 49 as well as in liquid phase systems such as electrochemical analysis, 50 electroosmotic processes, 51 or electrochemical energy storage. 52 Both PIM-1 and PIM-EA-TB have been employed previously for embedding catalysts 53 with the aim of minimizing catalyst surface blocking by avoiding detrimental PIM-catalyst interactions (due to molecular rigidity in the polymer backbone) and maximizing catalyst performance (due to a fully accessible catalyst surface 54 ).…”

Switching ionic diode states with proton binding into intrinsically microporous polyamine films (PIM-EA-TB) immersed in ethanol

“…The observation of rectified ion transport has been linked to the associated rectified electroosmotic transport of water solvent molecules [6,7] and other small guest molecules such as caffeic acid [8]. Most studies to date have addressed behaviour of ionic diodes in aqueous media with applications for example in desalination [9,10], in energy conversion [11], or in sensing [12][13][14]. Current gating, for example with applied potentials or with ionic species, has been reported in nanopores and in nanochannels [15,16].…”

A critical insight into porous organic polymers (POPs) and its perspectives for next-generation chemiresistive exhaled breath sensing: a state-of-the-art review

“…10 In general, POPs can be subdivided into amorphous (Fig. 3) and crystalline, in which amorphous POPs are categorized as hypercrosslinked polymers (HCPs), 39 polymers of intrinsic microporosity (PIMs), 40 conjugated microporous polymers (CMPs), 41,42 and porous aromatic frameworks (PAFs). 43 On the other hand, covalent organic frameworks (COFs) 44,45 and covalent triazine frameworks (CTFs) 46 (Fig.…”

“…11), with a constant exposure for 30 min, conrming that COF-DC-8 has a p-type behavior. 53 On the other hand, COF-DC-8 displayed negative sensing responses of 3939 ± 317% and −6338 ± 479%, respectively, toward 40 The table presents the overview of the sensing signatures of the POPs reported for chemiresistive sensing.
