Positively charged colloidal drug carriers have shown interesting properties with respect to the negatively charged systems: they have improved stability in the presence of biological cations and their interaction with negatively charged biological membranes is facilitated. In the present work, a...
4-Dimethylamino-3-cyanobiphenyl (4-DMA-3-CB) was characterized with respect to linear and nonlinear optical properties in a crystal as well as in solution. The crystal structure was studied dependent on the crystallization conditions. It is shown that the crystal structure exhibiting NLO-activity...
