Photoluminescent coordination polymer bulk glasses and laser-induced crystallization.

We synthesized luminescent coordination polymer glasses composed of d metal cyanides and triphenylphosphine through melt-quenching and mechanical milling protocols. Synchrotron X-ray total scattering measurements and solid-state NMR revealed their one-dimensional chain structures and high structural dynamics. Thermodynamic and photoluminescence properties were tunable by the combination of heterometallic ions (Ag, Au, and Cu) in the structures.

Proton-conductive coordination polymer glass for solid-state anhydrous proton batteries.

Designing solid-state electrolytes for proton batteries at moderate temperatures is challenging as most solid-state proton conductors suffer from poor moldability and thermal stability. Crystal-glass transformation of coordination polymers (CPs) and metal-organic frameworks (MOFs) melt-quenching offers diverse accessibility to unique properties as well as processing abilities. Here, we synthesized a glassy-state CP, [Zn(HPO)(HO)](1,2,3-benzotriazole), that exhibited a low melting temperature (114 °C) and a high anhydrous single-ion proton conductivity (8.

Coordination polymer glass from a protic ionic liquid: proton conductivity and mechanical properties as an electrolyte.

High proton conducting electrolytes with mechanical moldability are a key material for energy devices. We propose an approach for creating a coordination polymer (CP) glass from a protic ionic liquid for a solid-state anhydrous proton conductor. A protic ionic liquid (dema)(HPO), with components which also act as bridging ligands, was applied to construct a CP glass (dema)[Zn(HPO)(HPO)].

The role of lattice vibration in the terahertz region for proton conduction in 2D metal-organic frameworks.

We studied the relationship between proton conductivity and the terahertz-regime vibrations of two-dimensional MOFs. The results of spectroscopy studies clarified the essential role played by the collective motions in the terahertz region in 2D layers for efficient H conduction. calculations suggested the collective motion to be predominantly determined by the valence electronic structure, depending on the identity of the metal ion.
