Polycrystalline metal-organic framework (MOF) layers hold great promise as molecular sieve membranes for efficient gas separation. Nevertheless, the high crystallinity tends to cause inter-crystalline defects/cracks in nearby crystals, which makes crystalline porous materials face a challenge fabrication of defect-free membranes. Herein, first time, we demonstrate balance between and film formation MOF membrane through facile situ modulation strategy. Monocarboxylic acid was introduced modulator regulate via competitive complexation thus concomitantly control film-forming state during growth.
