Herein, we designed carbonyl\u2010rich molecules with extended arms to increase the density of hydrogen\u2010bond acceptors and enhanced benzene ring rotation to reduce \u03c0\u2010\u03c0 stacking, thereby strengthening hydrogen bonding to assist coordination\u2010driven assembly of HMOFs. Benefiting from strong hydrogen bonding between central carbonyl groups and metal ions to modulate metal coordination, a series of 2+2 layer\u2010interpenetrated HMOFs with different metal nodes (Co\n                    <jats:sup>2+<\/jats:sup>\n                    , Ni\n                    <jats:sup>2+<\/jats:sup>\n                    , and Zn\n                    <jats:sup>2+<\/jats:sup>\n                    ) were synthesized. Serving as interpenetration intersections, those metal nodes stabilize the framework via hydrogen bonding, together with the inter\u2010locked coordination framework and extensive hydrogen\u2010bonded network, endow the HMOFs with open channels and qualified stability. These HMOFs exhibit proton conductivity of \u223c10\n                    <jats:sup>\u22123<\/jats:sup>\n                    \u00a0S\u00a0cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 95\u00b0C and 98% relative humidity with activation energies all below 0.2\u00a0eV.
