Tyrian purple sea salt in the dye vat and adding potash, he was able to successfully dye wool a deep purple colour. Recent research in organic electronics has shown that Tyrian purple is an ambipolar organic semiconductor. Transistors and circuits based on this material can be produced from sublimed thin-films of the dye. The good semiconducting properties of the dye originate from strong intermolecular hydrogen bonding that reinforces pi stacking necessary for transport. True Tyrian purple, like most high-chroma pigments, cannot be accurately rendered on a standard RGB computer monitor. Ancient reports are also not entirely consistent, but these swatches give a
HMS Tyrian (R67) pennant number F67. From August 1952 until 1956 she was part of the 2nd Training Squadron at Portland.
