General description

N749 Black Dye (N749) has ruthenium at the center that forms a co-ordinate bond with the monoprotonated tricarboxyterpyridine and three thiocyanates. It can be used as a sensitizer that functionalizes the semi-conducting materials that exhibit an absorption peak in the near infrared region.

Application

N749 Black Dye is designed for the widest range spectral sensitisation of wide band-gap oxide semiconductors; like titanium dioxide up to wavelengths beyond 800nm.
Recommended application in 0.2-0.3mM solution with ethanol or acetonitrile/tert-butanol (1:1; vol:vol).
Reduced graphene oxide (rGO) can be surface modified by using N749 to enhance the photocatalytic characteristics of hydrogen evolution system. It may also be used as a high efficiency dye for niobium pentoxide (Nb2O5) photoanodes which can be used for the fabrication of titanium oxide (TiO2) coated dye sensitized solar cells (DSSCs).

Ruthenium-based dyes for Dye-sensitized Solar Cells

Dye-sensitized solar cells (DSCs) are 3rd generation solar cells combining the promise of high efficiency with low production costs.

Understanding and Successfully Applying Materials for Dye-Sensitized Solar Cells

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm2.2
