Abstract
Most of the photonic crystal films have been studied with variety ionic liquids. The object of our research is to observe the expression of 1D lamellar photonic crystal color depending on amino chiral ionic liquids. Color changes of photonic crystal would be reported through a simple method. 1D lamellar photonic crystal was made by Poly Styrene-block-Poly-2- Vinyl Pyridine (52K-57K) in tetrahydrofuran (THF). After having done spin coating, we accomplished annealing. Amino chiral ionic liquids was made synthesized that L-Alanine tert butyl ester hydrochloride (L-AlaC4Cl) and L-valine tert butyl ester hydrochloride (L-ValC4Cl) was synthesized Bis(trifluoromethane) sulfonamidelithium salt (LiNTf2) respectively. The annealed photonic films was swelled to using synthesis amino chiral ionic liquids. A variety of color expressions was analyzed through UV visible spectrometer.
