The global quest for clean energy and sustainable processes makes advanced membrane extremely attractive energy-intensive industrial gas separations. Here, we disclosed a series of ultra-high-performance separation membranes (PIM-3D-TB) from novel network polymers intrinsic microporosity (PIM) that combine the advantages solution processible PIM small pore size distribution (PSD) porous organic (POP), which was synthesized by in situ copolymerization triptycene-2,6-diamine as linear part triptycene-2,6,13(14)-triamine (TTA) crosslinker. resulting PIM-3D-TB demonstrated outstanding properties outperformed latest trade-off lines H2/CH4 O2/N2. They also showed an anti-trade-off effect simultaneously enhancing permeability gas-pair selectivity with increasing TTA content. crosslinking node increased microporosity, and, shifted PSD ultramicropore (<7 Å) toward more sieving submicropore (<4 region. post-treated TTA-75 displayed exceptional H2 8000 Barrer 208. These their design protocol have unparalleled potential next generation hydrogen purification air

Advanced Microporous Framework Membranes for Sustainable Separation

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 24, 2025

Abstract Advancements in membrane‐based separation hinge on the design of materials that transcend conventional limitations. Microporous materials, including metal–organic frameworks (MOFs), covalent–organic (COFs), macrocycles, and porous organic cages (POCs) offer unprecedented control over pore architecture, chemical functionality, transport properties, making them promising candidates for next‐generation membrane technologies. The well‐defined tunable micropores provide a pathway to directly address permeability‐selectivity trade‐off inherent polymer membranes. Here, this review explores latest advancements these four representative microporous membranes, emphasizing their breakthroughs hydrocarbon separation, liquid‐phase molecular sieving, ion‐selective transport, particularly focusing structure‐performance relationships. While tailored structures enable exceptional performance, practical adoption requires overcoming hurdles scalability, durability, compatibility with industrial processes. By offering insights into structure optimization innovative strategies, provides roadmap advancing membranes from laboratory innovation real‐world implementation, ultimately supporting global sustainability goals through energy‐efficient
