Ingenious Modulation of Third-Order Nonlinear Optical Response of Zr-MOFs through Defect Engineering Based on a Mixed-Linker Strategy

“…Third-order nonlinear optical (NLO) materials have been widely used in laser protection, biological imaging, photodynamic therapy, and logic devices. − Metal–organic frameworks (MOFs) exhibit exceptional potential for applications in the field of nonlinear optics owing to their customizable structure, adjustable electronic properties, and facile modifiability. − Currently, primitive MOFs are limited to a single charge transfer path either from metal to ligand or from ligand to metal, resulting in low efficiency of electron transfer. , Defect tuning in MOFs is an effective approach to address this issue. It is widely embraced to promote the properties of diverse materials, regulate their surface characteristics, and bestow novel and practical functionalities upon them. , The introduction of defects into MOFs can not only lead to a cascade of transformations, including the rupture and recombination of chemical bonds and distortion and rearrangement of electron clouds, but also engender new pathways for charge transfer, thereby effectively augmenting charge transfer efficiency. − The charge transfer efficiency is widely acknowledged as the pivotal factor influencing the performance of NLO, which possesses the potential to effectively regulate and optimize the overall functionality. − …”
