Photochromic Reaction of a Novel Room Temperature Ionic Liquid: 2-Phenylazo-1-hexyl-3-methylimidazolium Bis(pentafluoroethylsulfonyl)amide
We synthesized a new room temperature ionic liquid, [2PA-Hmim][Pf(2)N], and characterized the photochromic behavior by absorption spectroscopy. [2PA-Hmim][Pf(2)N] was found to be a photochromic liquid where solvent itself undergoes photochromic reaction.
