Precise control over chemical microenvironment within sub\u2010nanometer pores is critical but notoriously difficult to achieve in scalable materials like amorphous polymers. Here we report a strategy for engineering the microenvironments of confined channels in a polymer of intrinsic microporosity (PIM) by using hydrogen bonding to uniformly anchor oligoether chains onto the pore walls. The enhanced confinement effect resulting from this anchoring increases steric limitation for larger ions (e.g., Mg\n                    <jats:sup>2+<\/jats:sup>\n                    ) and strengthens their ion\u2010channel interactions. Concurrently, the uniformly distributed oligoether chains establish a synergistic transport pathway for small ions (e.g., Li\n                    <jats:sup>+<\/jats:sup>\n                    ). The resulting membrane exhibits exceptionally high selectivity for monovalent ions over divalent ions (Li\n                    <jats:sup>+<\/jats:sup>\n                    \/Mg\n                    <jats:sup>2+<\/jats:sup>\n                    selectivity of &gt;270) while maintaining a high Li\n                    <jats:sup>+<\/jats:sup>\n                    flux (&gt;0.6\u00a0mol m\n                    <jats:sup>\u22122<\/jats:sup>\n                    h\n                    <jats:sup>\u22121<\/jats:sup>\n                    )\u2014an order of magnitude improvement compared to state\u2010of\u2010the\u2010art polymeric membranes.
