제목 Modification of basic dyes with weakly coordinating bulky anions for improving their solubilities in organic solvents without color change
초록 Basic dyes are popularly used commercial dyes due to their advantage in optical property and price. Basic dyes show superior solubilities in water, but, they are rarely dissolved in organic solvents due to their ionic characteristics. To overcome this problem of basic dyes, we designed basic dyes with weakly coordinating anions (WCAs) that have no effect on the spectral properties of the dyes.
Unmodified basic dyes generally show superior solubilities in polar protic solvents. However, the dyes with WCAs showed improved solubilities in polar aprotic solvents and non-polar solvents. The zeta potentials and XRD patterns were also measured to analyze the change of their molecular characteristics by the introduction of WCAs.
The modification by WCAs had no effects on the optical performances of the dyes and the color filters. Namely, by the introduction of the WCAs, it is possible to increase the solubilities of basic dyes in organic solvents without any discoloration to them.
