General description

Disperse Red 1 (DR1) is a non-linear optical (NLO) material which is a chromophore used as an azobenzene dye. It can form a dipole network that can enhance the electro-optic effect of the non-linear components and can also improve the photorefractive effect.

Application

DR1 dye can be incorporated into hydroxypropyl cellulose (HPC) matrix which can be used as a coating that finds potential application in light storage and photonics. It can also be used to evaluate the third order non-linear susceptibility (X(3)) for 1,3-indandione based glasses for use in optical frequency conversion. Polytetrafluoroethylene (PTFE) membranes modified using DR1 maintain the mass transport and diffusion properties under direct light irradiation and can be used for water desalination applications.

Features and Benefits

This benchmark dipolar chromophore was incorporated into aromatic polymers to obtain model electrooptic polymer films.
