Ferroelectricity results from one of the most representative phase transitions in solids, and is
widely used for technical applications. However, observations of ferroelectricity in organic …

In conventional ferroelectrics the polarization is induced either by the relative displacement
of positive and negative ions due to a lattice distortion or by the collective alignment of …

Tessellation of organic polygons though [π··· π] and charge-transfer (CT) interactions offers a
unique opportunity to construct supramolecular organic electronic materials with 2D …

Quantum phase transition achieved by fine tuning the continuous phase transition down to
zero kelvin is a challenge for solid state science. Critical phenomena distinct from the effects …

The π-electronic functionalities of molecular donor (D)–acceptor (A) compounds have been
attracting subjects for the solid state science as well as for the prospective technological …

Neutral–ionic (NI) phase transition is a reversible switching of organic charge-transfer
complexes between distinct valence states by external stimuli. This phase transformation in …

Organic charge-transfer (CT) crystals constitute an important class of functional materials,
