ABSTRACT
Accepted: 20 October 2020
A semi-organic single crystal named tris(cyclohexylammonium) tris(ochlorobenzoate) dihydrate (TCTCDH) had been successfully grown applying slow evaporation procedure. The developed crystal was involved for various characterization techniques. The structural property of the sample had been analyzed employing powder XRD study. The FT-IR spectral study was applied to confirm the existence of functional groups in the title compound. The optical property of the grown material has been explored using UV-visible NIR spectral study. The dielectric constant and dielectric loss were calculated to analyze the electrical property of the titular crystal. The third-order nonlinear susceptibility of the grown material was studied employing Z-scan technique using semiconductor laser at 532 nm. The thermal behavior of TCTCDH compound was ascertained using thermo-gravimetric analysis (TGA) and differential scanning calorimetry (DSC) analysis. The Vicker’s hardness study was employed to determine the mechanical stability of TCTCDH compound.

telecommunication systems and optical sensors [1]. Organic nonlinear optical materials are needed for optoelectronic applications owing to their high nonlinear activity, structurally more diverse and superior flexibilities but such materials suffer from disadvantages like poor mechanical and thermal strength [2].

The inorganic materials afford advantages such as high mechanical strength and good physiochemical stability. However, inorganic NLO crystals possess disadvantages, like modest optical nonlinearity and structural inflexibility [3]. In order to combine the advantages of organic and inorganic materials, a new class of materials has been proposed namely, the semi organics [4–7]. A new strategy of synthesizing organic–inorganic hybrid compounds has recently been very successful. Consequently, current research work focus on semiorganic materials because of their effective nonlinea
