title: Water-Stable Homochiral Cluster Organic Frameworks Built by Two Kinds of Large Tetrahedral Cluster Units.
abstract: 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 T3 -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).
