Crystal growth and characterization of the organic salt 4‐<i>N, N</i>‐dimethylamino‐4′‐<i>N</i>‐methyl‐stilbazolium tosylate (dast)

The growth of bulk crystals of organic salts with large chromophoric has received little attention, despite the importance of crystal quality for both applications and research. Here, the growth of the title compound (DAST), see Figure, is reported and the main results of the linear, nonlinear, and electro‐optical characterization are presented DAST is shown to be of interest for nonlinear optical applications. magnified image
