Flexible organic ferroelastic crystals via solution pH engineering
Zeng-Jie Xiao, Ya-Ting Zou, Peng-Cheng Zhuge, Cha-Hui Du, Ji Liu, Lei Pan, Hao-Fei Ni, Lou-Kai Ye, Ya-Yuan Luo, Yi Zhang, Zhi-Xu Zhang, Da-Wei FuTuning solution pH to alter cation protonation enables the emergence of ferroelasticity. A monoprotonated crystal exhibits no ferroelasticity, while a diprotonated crystal shows multiple phase transitions and stable ferroelastic domains.
