PROBLEM TO BE SOLVED: To provide a coloring matter for organic laser, having excellent durability against light irradiation and emitting light in high efficiency. SOLUTION: There is provided a fluorescent coloring matter exhibiting high stability (against oxidation reaction, radical reaction, photoreaction or the like) and highly efficient light emission (high absorbance and high quantum efficiency), and capable of being dispersed in a polymer or a liquid crystal solvent in high concentration. Concretely, there is provided the compound obtained by introducing aryl groups to easily oxidizable four points of pyrene and two points of anthracene, and further introducing dissolvable long-chain alkyl groups to the aryl groups. These coloring matters especially are aimed at organic lasers oscillating at low thresholds and continuous oscillation thereof. COPYRIGHT: (C)2011,JPO&INPIT
