Atomic structure of the continuous random network of amorphous C[(C6H4)2]2, PAF-1
Guanqun Cai, He Lin, Ziqiang Zhao +11
We demonstrate that the amorphous material PAF-1, C[(C6H4)2]2, forms a continuous random network in which tetrahedral carbon sites are connected by 4,4'-biphenyl linkers. Experimen…

Colossal pressure-induced softening in scandium fluoride
Zhongsheng Wei, Lei Tan, Guanqun Cai +4
The counter-intuitive phenomenon of pressure-induced softening in materials is likely to be caused by the same dynamical behaviour that produces negative thermal expansion. Through…

Hydrogen-bond-mediated structural variation of metal guanidinium formate hybrid perovskites with unit cell volume
Zhengqiang Yang, Guanqun Cai, Craig L. Bull +4
The hybrid perovskites are coordination frameworks with the same topology as the inorganic perovskites, but with properties driven by different chemistry, including host-framework…
