Synthesis, crystal growth and spectroscopic investigation of second order organic nonlinear optical single crystal: 2-Chloro-N-[4-(dimethylamino)benzylidene]aniline

- First time single crystal of 2Cl4DBA was grown by slow evaporation technique from synthesized compound.
- NMR, FTIR spectral analysis and XRD technique were used to confirm the product formation.
- Good thermal stability of the grown crystal is up to 135 °C.
- SHG efficiency of title crystal was more than that of standard KDP and urea material.
