Methanol–water mixture evaporation-induced self-assembly of ZIF-8 particles.

We report a strategy for the self-assembly of zeolitic imidazolate framework-8 (ZIF-8) particles induced by the evaporation of a methanol–water mixture. This strategy effectively suppresses the coffee ring effect, facilitates the rapid assembly of ZIF-8 particles, and improves the orientation and optical properties of self-assembled superstructures.
