Third-Order Nonlinear Optical Modulation Behavior of Photoresponsive Bimetallic MOFs

“…With the development of optics and optoelectronic technology, metal–organic frameworks (MOFs) have attracted much attention in the field of third-order nonlinear optics (NLO) due to their customizable structures and flexible coordination modes. − In previous reports, the design strategy for MOFs with excellent NLO performance was typically aimed at the modification of ligands, such as extending the π-conjugated length of the ligands or introducing strong electron donor/acceptor groups. − Notably, charge transfer between ligands and metal ions (including metal to ligand and ligand to metal) is considered a key factor affecting the nonlinear performance of MOFs. − However, the single metal node and uniform charge density distribution often lead to low efficiency between ligands and metal ions; − therefore, constructing bimetallic cooperative MOFs is an effective strategy to regulate charge transfer from the aspect of the internal structure and improve the performance of third-order NLO. , …”

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

“…7−10 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. 11,12 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.…”

“…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. − …”
