Description
Summary:	[Display omitted] •Novel non-centrosymmetric Cadmium Metal-Organic Framework (Cd-MOF) crystal with chemical formula CdC8N8H14O2S4 have been prepared by a slow solvent evaporation method.•UV–Vis absorption spectrum in DMSO solvent revealed absorption maximum peak at 277 nm.•Fluorescence spectrum of the crystal showed a peak at 330 nm in DMSO solution.•The Z-scan plots show a strong self-defocusing and a strong reverse saturable which occur as a third-order susceptibility at order of 10-6esu.•The crystal exhibits optical limiting phenomenon with optical limiting threshold value of 1094 kW/cm2. A novel non-centrosymmetric Cadmium Metal-Organic Framework (Cd-MOF) crystal with chemical formula CdC8N8H14O2S4 was synthesized and characterized. The band structure and optical limiting properties of the Cd-MOF were investigated using Band structure calculations and Optical limiting studies. The band structure analysis showed that the crystal displayed a larger, highly dispersive band, highlighting significant anisotropic n-channel charge carrier mobility. The optical limiting study demonstrated that the Cd-MOF exhibited Reverse Saturable Absorption (RSA) behaviour with an optical limiting threshold value of 1094 kW/cm2. The NLO behaviour of the Cd-MOF provides a promising potential for its application in NLO devices.
