Abstract

A two-dimensional (2D) Co-based metal-organic framework (MOF) with porphyrinic skeleton forms crystalline plates, flower-shaped clusters, and ultrathin films under optimized conditions, including the use of polyvinylpyrrolidone (PVP) as a surfactant. Ultrathin films demonstrate the best solution-based third-order nonlinear optical properties, featuring a nonlinear transmittance (T) value of 0.54, absorption coefficient (α 2 ) of 9.5 × 10 −10 m W −1 and second hyperpolarizability (γ) value of 1.37 × 10 −28 esu, which are slightly better than those of the flower-shaped clusters (T = 0.65, α 2 = 7.0 × 10 −10 m W −1 ; γ = 1.27 × 10 −28 esu), but marginally better than those of the crystalline thin plates (T = 0.94, α 2 = 2.4 × 10 −10 m W −1 ; γ = 0.24 × 10 −28 esu).
