• InChI Key: MOFVSTNWEDAEEK-UHFFFAOYSA-M
• Solubility: SOL IN WATER & METHANOL; PRACTICALLY INSOL IN MOST OTHER ORG SOLVENTS;Soluble in water, less soluble in ethanol.
• Appearance: Light yellow to Amber to Dark green powder to crystal
• Application: Applications using these organic dyes include security markings, lithography, optical recording media and optical filters. In order to increase power conversion efficiency of an organic solar cell, efficient near infrared dyes are required, because sunlight includes near infrared light. Furthermore, near infrared dyes are expected to be biomaterials for chemotherapy and imaging deep-tissue in-vivo by using luminescent phenomena in the near infrared region.
