PLASTIC CRYSTAL ELECTROLYTE COMPOSITION WITH CHEMICAL CROSS-LINKED STRUCTURE

摘要

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 area 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, and n indicates 0 or 1. Here, the substituents of R1 - R8 are selected from the alkyl group having 1-5 carbons and halogen except the fluorine. The near infrared ray absorption filter includes the diimonium group compound.
