General description
Disperse Red 19 (DR19) is widely used as a non-linear optical (NLO) dye with two hydroxyl (OH) groups, which can covalently connect with the base polymer. It can be linked as a side chain group that provides thermal and photo stability to the polymeric unit.
Application
DR19 can be used as red side groups in an NLO polyester for potential application in optical switching devices. It can also be bonded with polyurethane to form stable films, which may be used in the fabrication of analog systems.
