Basic blue 7, basic blue 26, ethyl violet, lithium bis(trifluoromethanesulfonyl)imide, and lithium bis(oxalato)borate were purchased from TCI. Propylene glycol methyl ether acetate was purchased from Sigma-Aldrich. Methylene chloride, chloroform, and other chemical solvents were purchased from Samchun Pure Chemical. All chemicals were used without any additional purification. Transparent glass substrates were provided by Paul Marienfeld GmbH & Co.KG and acrylic binder was supplied by Alphachem Corporation.
Absorption and transmittance spectra were measured using a Perkin Elmer Lambda 25 UV/Vis spectrophotometer. Chromatic characteristics of the color films were analyzed on a Scinco color spectrophotometer. X-ray diffraction patterns were measured using Bruker New D8 Advance X-Ray Diffractometer. 1H and 13C Nuclear Magnetic Resonance (NMR) spectra were recorded on a Bruker Avance 500 spectrometer running at 500 MHz using chloroform-d as a solvent with TMS as an internal standard. Mass spectra were obtained using an LCQ Fleet mass spectrometer with high resolution.
