The present invention relates to a cationic compound denoted by the general formula (I). In general formula (I), Ar
1
and Ar
2
each independently denote an optionally substituted aryl group or aromatic heterocyclic group, L
1
denotes a single bond or a divalent linkage group, with at least one from among Ar
1
, Ar
2
and L
1
comprising one or more onium cations; R
3
and R
4
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 R
3
s and R
4
s may be identical or different from each other when m3 and m4 are an integer ranging from 2 to 4.
本发明涉及一种由一般式(I)表示的阳离子化合物。在一般式(I)中,Ar1和Ar2各自独立地表示可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,其中至少有一个来自于Ar1、Ar2和L1中的一个或多个离子上阳离子;R3和R4各自表示取代基团,并且可以与苯环取代形成环;m3和m4各自独立地表示从0到4的整数,当m3和m4为从2到4的整数时,复数的R3和R4可能相同也可能不同。
