| Hazard Information | Back Directory | [Description]
N749, [(C4H9)4N]3[Ru(Htcterpy)(NCS)3],?also referred to as "black dye", was developed for the widest range spectral sensitisation of wide band-gap oxide semiconductors (like titanium dioxide up to wavelengths beyond 800nm). ?N749 black dye is a ruthenium complex, in which the ruthenium center contains one terpyridine ligand substituted with three carboxyl groups and three thiocyanato ligands | [Uses]
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). | [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. |
