Abstract

A compound represented by (Tr)-Z is useful as a host material for delayed fluorescent materials. Tr represents a substituted or unsubstituted triphenylenyl group, and plural Tr's existing in the general formula (1) may be the same as or different from each other. Z represents a carbonyl group or a substituted or unsubstituted, n-valent aromatic hydrocarbon group. n represents an integer of 2 to 6, but when Z is a carbonyl group, n is 2.
