| Application: | DO3 can be used in low concentration to improve the electro-optic properties of dichroic polymer-dispersed liquid crystals, which can be used as materials for display devices. It can also be used to functionalize epoxy-bisazo based polymers, which can be potentially used in sensors and optoelectronics. |
| Features and Benefits: | Used to provide experimental verification of a two-level model for the enhancement of the nonresonant, nonlinear refractive index, with a decrease in absorption by reduction of a donor group strength. |
| General description: | Disperse Orange 3 (DO3) is a monoazo dye, which contains 90% dye content plus dispersing agents and surfactants. It has two aromatic rings with an amino group on one of the rings and the other is substituted with a nitro group. It shows an absorption peak majoring at 415 nm. |
