Compared with metal organic frameworks (MOFs), the proton conductivity of cluster organic frameworks has been less studied. Herein, two supertetrahedral cluster organic frameworks (SCOFs) have been made that show two‐fold interpenetrated networks built by trivalent lanthanide tetrahedral clusters and monovalent cuprous T 3 ‐supertetrahedral clusters. The structure analysis, second harmonic generation signals, and solid‐state circular dichroism spectroscopy consistently reveal the chirality of these SCOFs. Remarkably, the water‐stable SCOFs show a high proton conductivity value of 1.4×10 −3 S cm −1 at 80 °C and 95 % RH (relative humidity).
