A 3D anionic In3+–MOF integrates the multifunctionality of pure blue luminescence with a high quantum yield of 61.4% and water-mediated fast proton conduction with σ = 2.90–9.22 × 10−3 S cm−1 at 25–60 °C and 99% RH.

A water stable proton-conducting material (NH4)5[Zr3(OH)3F6(PO4)2(HPO4) (ZrP) was hydrothermally synthesized. The three-dimensional (3D) framework of ZrP is composed of ZrF2O4 octahedra and HxPO4 phosphate units and forming 18-ring channels through...

In this work, we present a new strategy toward the design and preparation of a metal−organic framework-or porous coordination polymer-based superior proton conductor. We chose a robust metal−organic framework, ZIF-8, as the host and a flexible aliphatic alkylpolyamine, tetraethylenepentamine (TEPA), as the guest, and we successfully prepared an encapsulation compound TEPA@ ZIF-8 via the facile insertion of TEPA into the pores of ZIF-8, which was characterized by microanalysis, thermogravimetric analysis, IR spectroscopy, N 2 , water vapor adsorption− desorption, and other methods. Each cage in ZIF-8 is occupied by ∼1.

Open-framework zinc phosphate (NMe4)(ZnP2O8H3) undergoes irreversible phase transformation. Structural transformation with α (NMe4.Zn[HPO4][H2PO4] the low-temperature phase) and β (NMe4.ZnH3[PO4]2 the high-temperature phase) (Tc=149 °C) and conduction properties were investigated by...

Crystal structure diversity and dimensionality of three Mg2+-based CPs, which emit bright ligand-based luminescence at ambient conditions, are modulated by reaction temperature and structural induction agents.
