    • PURPOSE: A diimonium based compound and a near infrared ray-absorbing filter using the same are provided to display wide and even absorption rate in the near infrared ray region and to improve durability and weatherability. CONSTITUTION: A diimonium based compound has a structure which is represented by chemical formula 1. In the chemical formula 1, R1 - R8 are respectively and independently indicate hydrogen atom(H), substituted or non-substituted aryl having 6-14 carbons, or substituted or non-substituted alkyl group having 1-10 carbons. In the chemical formula 1, n indicates 0 or 1. The substituents of R1 - R8 are selected from the alkyl group having 1-5 carbons and halogens except fluorine. The near infrared ray absorbing filter includes the diimonium based compound.
    • 目的:提供使用二马来酰亚胺化合物和使用其的近红外线吸收滤光片,以在近红外线区域显示出宽的均匀的吸收率,并提高耐久性和耐气候性。 化学式1中,R 1 -R 8分别独立地表示氢原子(H),具有6-14个碳原子的取代或未取代的芳基,或者 具有1-10个碳原子的取代或未取代的烷基。 在化学式1中,n表示0或1.R 1 -R 8的取代基选自具有1-5个碳原子的烷基和氟以外的卤素。 近红外线吸收滤光器包括二亚铵基化合物。
