| abstract |
The present invention provides a novel compound having an excellent property to inject a hole into a device such as an organic EL device. More specifically, the present invention provides a compound comprising a residue obtained by removing at least one hydrogen atom from a structure represented by the following formula (1): n nwhereinn each R 1 represents a hydrogen atom, an alkyl group, or the like, each of such groups optionally having a substituent; the R 1 s may be the same or different; each R 2 represents a hydrogen atom, an alkyl group, or the like, each of such groups optionally having a substituent; the R 2 s may be the same or different; each R 4 represents a hydrogen atom, an alkyl group, or the like, each of such groups optionally having a substituent; the R 4 s may be the same or different; each R 15 represents an alkyl group or the like, each of such groups optionally having a substituent; where there are a plurality of R 15 , they may be the same or different; each e represents an integer of from 0 to 6; and the e's may be the same or different. |
