Claim:
A compound expressed by following general formula (IV): wherein, in the general formula (IV), Ar 41 represents a divalent aryl group or heterocyclic group; R 42 represents an aryl group, heterocyclic group, or aliphatic hydrocarbon group; R 44 represents a heterocyclic group, perfluoroalkyl group, cyano group, oxycarbonyl group, carbamoyl group, sulfonyl group, sulfamoyl group, or R (C═X)-group; R 45 represents a hydrogen atom, cyano group, perfluoroalkyl group, oxycarbonyl group, carbamoyl group, sulfonyl group, sulfamoyl group, or R (C═X)-group; R represents an aliphatic hydrocarbon group, aryl group, or heterocydic group; X represents an oxygen atom, sulfur atom, N—R A1 , or CR A2 R A3 ; R A1 ; R A2 and R A3 each independently represents a hydrogen atom or substituent, excluding a case in which —R A2 and R A3 are both hydrogen atoms; R 46 , R 47 , and R 48 each independently represents a hydrogen atom or substituent; m represents 0, 1, or 2; n represents an integer no less than 2; two or more combinations of Ar 41 , R 42 , R 44 ; R 46 ; R 47 , R 48 , and m may be the same or different; L represents a linkage group having a valence of n; and at least two of the Ar 41 , R 42 , and L each independently represents an aryl group or heterocyclic group.
