Abstract

-TPPE-2D exhibited a much higher value, approximately 6.76 times that of the other two MOFs. Structure analysis and density functional theory calculations revealed that the characteristic TPEF properties are closely related to the molecular geometry and molecular interactions. This work expands the utilization of TPEF secondary building blocks and can bring some new insights into the design of high-efficiency TPEF-MOF materials.
