Strain-Mediated Second Harmonic Generation Enhancement of Bimetallic Metal-Organic Frameworks.

Triggered by the demand of developing practical metal-organic framework (MOF) based nonlinear optical (NLO) devices, there is a surge of research interest in the regulation of NLO properties of MOFs. Strain engineering provides a new opportunity to regulate the optoelectronic properties of materials and device performance at the interface. Here we introduce the induction of the strain field in structures by constructing bimetallic Zn/Cu-MOFs.
