Metal–organic frameworks (MOFs), as a porous frame material, exhibit considerable electrical conductivity. In recent decades, research on the proton conductivity of MOFs has made gratifying progress. In this review, the designable guest molecules encapsulated into MOFs are summarized and generalized into four types in terms of promoting proton conductive performance, and then recent progress in the promotion of proton conductivity by MOFs encapsulating guest molecules is discussed. The existing challenges and prospects for the development of this strategy for promoting MOFs’ proton conductivity are also listed. How to welcome guests: In this review, we summarize the current strategies for introducing guest molecules into MOFs to improve their proton conductivity, and divide the guest molecules into four types. We also present the challenges and prospects of applying this strategy for these solid proton conducting materials.
