Switchable dielectric phase transition in tris(1-(chloromethyl)-1,4-diazabicyclo[2.2.2]octane) tetra(tetrafluoroborate) dichloride

Two novel metal–organic coordination polymers based on ligand 1,4-diazabicyclo[2.2.2]octane N,N′-dioxide with phase transition, and ferroelectric and dielectric properties

The synthesis of two low-temperature structural phase transition compounds {[Ag₃(dabcodo)(NO₃)₃]·H₂O}n (1) and [Ca(Dabcodo)(H₂O)₄Cl₂]_n (2) are described. Compound 1 displayed ferroelectric–ferroelectric phase transition.

Orientational ordering of guest induced structural phase transition coupled with switchable dielectric properties in a host–guest crystal: bis(thiourea) thiazolium chloride

A host–guest crystal: (thiazolium)[(thiourea)₂Cl] undergoes order-disorder structural phase transition at 213.7 K, accompanied by distinct switchable dielectric responses.
