The present invention relates to a cationic compound denoted by the general formula (I). In general formula (I), Ar1 and Ar2 each independently denote an optionally substituted aryl group or aromatic heterocyclic group, L1 denotes a single bond or a divalent linkage group, with at least one from among Ar1, Ar2 and L1 comprising one or more onium cations; R3 and R4 each independently denote a substituent and may form a ring with a benzene ring substituted; m3 and m4 each independently denote an integer ranging from 0 to 4, and plural R3s and R4s may be identical or different from each other when m3 and m4 are an integer ranging from 2 to 4.
本发明涉及通式(I)表示的阳离子化合物。在通式(I)中,Ar1 和 Ar2 各自独立地表示任选取代的芳基或芳香杂环基团,L1 表示单键或二价连接基团,Ar1、Ar2 和 L1 中至少有一个包含一个或多个鎓阳离子;R3和R4各自独立地表示一个取代基,并可与被取代的苯环形成一个环;m3和m4各自独立地表示0至4的整数,当m3和m4为2至4的整数时,多个R3s和R4s可彼此相同或不同。
