The present invention provides a filter for electronic display devices, comprising a squarylium compound represented by General Formula (I):
[wherein R1 and R2 may be the same or different and each represents a hydrogen atom, an alkyl group optionally having substituent(s), an aralkyl group optionally having substituent(s), an aryl group optionally having substituent(s), or a heterocyclic group optionally having substituent(s); X represents a group represented by following Formula (A):
(wherein R3 and R4 may be the same or different and represents a hydrogen atom, an alkyl group optionally having substituent(s), an alkoxy group optionally having substituent(s), an aralkyl group optionally having substituent(s), an aryl group optionally having substituent(s), or a heterocyclic group optionally having substituent(s), wherein R3 and R4 may be combined together with the adjacent nitrogen atom thereto form a heterocyclic group optionally having substituent(s))].
本发明提供了一种用于电子显示设备的滤波器,由通式 (I) 所代表的鳞片状化合物组成:
[其中 R1 和 R2 可以相同或不同,各自代表氢原子、可选具有取代基的烷基、可选具有取代基的芳烷基、可选具有取代基的芳基或可选具有取代基的杂环基;X 代表下式(A)所代表的基团:
(其中 R3 和 R4 可以相同或不同,代表氢原子、任选具有取代基的烷基、任选具有取代基的 烷氧基、任选具有取代基的芳烷基、任选具有取代基的芳基或任选具有取代基的杂环基,其中 R3 和 R4 可与相邻的氮原子结合形成任选具有取代基的杂环基)]。
