A Cu(I)-Based MOF with Nonlinear Optical Properties and a Favorable Optical Limit Threshold.

ABSTRACT: The exploitation of high-performance third-order nonlinear optical (NLO) materials that have a favorable optical limit (OL) threshold is essential due to a rise in the application of ultra-intense lasers. In this study, a Cu-based MOF (denoted as Cu-bpy) was synthesized, and its third-order NLO and OL properties were investigated using the Z-scan technique with the nanosecond laser pulse excitation set at 532 nm. The Cu-bpy exhibits a typical rate of reverse saturable absorption (RSA) with a third-order nonlinear absorption coefficient of 100 cm GW^-1 and a favorable OL threshold of 0.75 J cm^-2 (at a concentration of 1.6 mg mL^-1), which is lower than that of most NLO materials that have been reported on so far. In addition, a DFT calculation was performed an
