Growth, crystal structure, thermal, spectral studies and density functional theory computational analysis of an organic nonlinear optical crystal: 2‐{3‐[2‐(4‐dimethylaminophenyl)vinyl]‐5,5‐dimethylcyclohex‐2‐enylidene}‐malonitrile

We report on synthesis, growth and characterization of an organic nonlinear optical (NLO) crystal 2‐{3‐[2‐(4‐dimethylaminophenylvinyl]‐5,5‐dimethylcyclohex‐2‐enylidene}‐malonitrile (DAT2). The functional groups are identified by 1H‐NMR. Large size single crystal of DAT2 of size 1.2 × 0.5 × 0.2 cm3 i...
