All these results indicated that the nonlinear optical activities could be enhanced by introducing suitable additional heteroatoms into donor moiety.

The colors and optical activities of these nanofibers can be maintained on an indium-tin oxide (ITO) coated electrode with a dedoping/redoping treatment.

The optical activities of the helical PANI nanofibers reversibly varied with different oxidized forms, which were easily controlled by the different potentials applied to the nanofibers.

We report on the synthesis and characterization of new crosslinked polymeric matrices functionalized with heterocycle-based dyes, showing enhanced second and third order nonlinear optical activities.

A compound that displays this ability is called optically active (see optical activity).

In this type of reactions there is a inversion of optical activity from R to S or vice versa in optically active compounds.
