Rational Design and Syntheses of Molecular Phase Transition Crystal Materials

Reversible phase transition materials (PTMs), of which their photoelectric responses can be modulated upon external heat, pressure, or light, have attracted great interest because of the potential applications for electronic, optical, and energy-based devices. The design strategy of chemical flexible structural components has great feasibility to construct new PTMs with outstanding photoelectric activities. Here, this paper presents our efforts on the design and syntheses of phase transition crystalline materials, as well as the related photoelectric effects. These unique physical properties make them potential candidates as switchable dielectrics, nonlinear optical switches, pyroelectric sensors, etc.
