New Yellow Aromatic Imine Derivatives Based on Organic Semiconductor Compounds for Image Sensor Color Filters

Novel aromatic imine derivatives with yellow were designed and synthesized for their potential application in color filters for image sensors. The synthesized compounds possessed chemical structures using aromatic imine groups. This innovative material was evaluated thoroughly, considering its optical and thermal properties under conditions similar to commercial de-vice manufacturing processes. Following a rigorous performance evaluation, it was found that (E)-3-methyl-4-((3-meth-yl-5-oxo-1-phenyl-1H-pyrazol-4(5H)-ylidene)methyl)-1-phenyl-1H-pyrazol-5(4H)-one, abbreviated as MOPMPO, exhibited an impressive solubility of 0.5 wt% in propylene glycol monomethyl ether acetate, predominantly utilized as the solvent in the industry. Furthermore, MOPMPO showed exceptional performance as a color filter material for image sensors, having a high decomposition temperature of 290 degrees C. These data unequivocally establish MOPMPO as a viable yellow dye additive for coloring materials in image sensor applications.
