Abstract 2D transition metal dichalcogenides (TMDs) have emerged as promising materials for advanced gas sensing platforms owing to their abundant active edge sites, high surface area, and mechanical flexibility. However, TMDs encounter low selectivity issues they show responses a variety of gases, impeding practical use discrimination. Herein, it is demonstrated that in situ growth breathable zeolitic imidazolate framework‐leaf (ZIF‐L) dramatically enhances the SnS 2 ‐based sensors H S. ZIF‐L selectively allows permeation target gas, S, while blocking interfering including C 3 9 N, NH , volatile organic compounds. The ZIF‐L/SnS sensor shows ultrahigh response (1440% resistance change) exceptional (response ratio > 10.2 about gases) 50 ppm S with theoretical detection limit 3.61 ppb. First‐principles calculations elucidate molecular sieving effect ZIF‐L, size exclusion adsorptive sieving, supporting mechanism outstanding selectivity. Additionally, monolithic flexible using polyethylene terephthalate substrate proves potential ZIF‐L/TMDs heterostructures applications. This study provides novel strategy tuning developing high‐performance chemical MOF‐based layer.
