Abstract Nanofiltration membranes hold great promise for ion separation but often suffer from a trade‐off between selectivity and flux, limiting their use in precise processes. A key challenge is achieving control over pore orientation, as existing methods fail to provide real‐time, quantitative insights optimizing membrane structure performance. To address this, an innovative situ, real‐time technique developed that links alignment directly efficiency. Using β‐cyclodextrin model pore‐forming compound, fluorescent labeling enables continuous monitoring of orientation distribution during fabrication. This method the capture complete across entire surface, allowing adjustments design. approach provides quantification alignment, facilitating design NF with enhanced permeability. The optimized demonstrate exceptional Mg 2+ /Li + efficiency, factor 15.55 permeance 35.85 L m −2 h −1 bar , representing significant step forward high‐performance nanofiltration broad applications resource recovery, environmental remediation, water treatment.
