Development of molecular crystals with multiple switching properties
研究の背景 Background
With the trend of miniaturization of electronic devices, molecular materials with multifunctionality are generally regarded as potential candidates for next-generation information technology. Controlling the magnetic and electronic states by external stimuli will play a central role in this aspect. In our study, we design and synthesize molecular crystals with the electronic structures lying at the boundary of different local minima on the potential energy surfaces, aiming at realizing the controllable switching behavior and synergistic electric and magnetic field effects.
研究の目標 Outcome
Molecular crystals with dynamic transition (valence tautomerism, spin crossover, etc.) behavior or superparamagnetic behavior have been designed and synthesized. Polar crystalline samples were selected and characterized by electric measurements. Currently, pyroelectric effect from pure molecular origin (e.g. intramolecular electron transfer) has been observed in polar valence tautomerism crystals. Future work involves the development of light- and field-responsive dynamic polar crystalline materials.
