Versions Notes

Transition-metal inorganic nitroprussides have been found to have potential applications, ranging from gas storage and separations to photomagnetism, medical technologies, and electrochemistry [1,2]. Although great effort has been devoted to the design and synthesis of nitroprusside-based materials with various physical properties, reports on the thermo/photo-responsive properties of nitroprusside-based hybrids are still extremely scarce.
We herein present our recent work on nitroprusside-based hybrids with exceptional electrical, optical, and thermal properties (Figure 1). Namely, unusual “negative-positive” uniaxial thermal expansion switching and an “on-off” nonlinear optical switching behaviour were observed in (Me2NH2)[KFe(CN)5(NO)] [3]. Photoisomerization was realized for the first time in solid-state hybrid ferroelectrics that allow photo-switching between the ferroelectric ground state and the metastable state [4].
