New Yellow Quinoline Derivatives Including Dione Moiety for Image Sensor Color Filters br

New yellow quinoline-dione dye derivatives were designed and synthesized for use in image sensor color filters. The synthe-sized compounds have a basic chemical structure composed of quinoline and dione groups. New materials were evaluated on the basis of their optical and thermal properties under conditions mimicking those of a commercial device fabrication process. A comparison of their related performances revealed that, between the two prepared compounds, 2-(3-hydroxyquinolin- 2(1H)-ylidene)-1H-indene-1,3(2H)-dione (HQIDO) exhibited the superior performance as an image sensor color filter material, including a solubility greater than 0.5 wt% in propylene glycol monomethyl ether acetate solvent and a high decomposition temperature of 298 degrees C, respectively. The results suggest that HQIDO can be used as a yellow dye additive in an image sensor colorant
