Visa mer Rubrene (5,6,11,12-tetraphenyltetracene) is a red colored polycyclic aromatic hydrocarbon. Rubrene is used as a sensitiser in chemoluminescence and as a yellow light source in lightsticks. Visa mer As an organic semiconductor, the major application of rubrene is in organic light-emitting diodes (OLEDs) and organic field-effect transistors, … Visa mer Rubrene, like other polycyclic aromatic molecules, undergoes redox reactions in solution. It oxidizes and reduces reversibly at 0.95 V and −1.37 V, respectively vs SCE. When the cation and … Visa mer Several polymorphs of rubrene are known. Crystals grown from vapor in vacuum can be monoclinic, triclinic, and orthorhombic motifs. Orthorhombic crystals (space group Bbam) are obtained in a closed system in a two-zone furnace at ambient pressure. Visa mer WebbMeasurements of refractive index, therefore, afford a means of measuring the solubility of substances in rubber and were employed for determinations of the solubility of sulfur and of a common antioxidant, phenyl-β-naphthylamine. Sulfur in combination with rubber had a relatively greater effect on the refractive index than did sulfur in solution.

WebbWe define the index of refraction, n, of a material to be n = c v, where v is the observed speed of light in the material. Because the speed of light is always less than c in matter and equals c only in a vacuum, the index of refraction (plural: indices of refraction) is always greater than or equal to one.
