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.[1][2]

Application

DR19 can be used as red side groups in an NLO polyester for potential application in optical switching devices.[3] It can also be bonded with polyurethane to form stable films, which may be used in the fabrication of analog systems.[4][5]
