Optical properties of the dye Disperse Red 1 covalently bonded to HMS surface via a one-step procedure are strongly affected by the polarity at the silica surface, which is modulated by the amount of residual template molecules and ethoxy groups formed during extraction in refluxing hot ethanol.

Abstract
Optical properties of the dye Disperse Red 1 covalently bonded to HMS surface via a one-step procedure are strongly affected by the polarity at the silica surface, which is modulated by the amount of residual template molecules and ethoxy groups formed during extraction in refluxing hot ethanol.
