NLO Properties of Poled Azocarbazole-Epoxy Composites.

Azocarbazole dyes are organic molecules that have already shown potential in nonlinear optical applications in host-guest systems. These molecules should be covalently bound to a host polymer network. This can be easily achieved if the host polymer is an epoxy resin. The work reports synthesis and properties of four new azocarbazoles dyes bearing a hydroxy function, which enables binding to epoxy resin. [ABSTRACT FROM AUTHOR]
