1. A compound of formula (1),

OG Complex Work Unit Chemistry
wherein R1 to R9 are independently selected from a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms, a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 50 ring atoms, and a cyano group;
provided that adjacent two in one or more pairs selected from R1 and R2, R2 and R3, R3 and R4, R4 and R5, R6 and R7, R7 and R8, and R8 and R9 may be bonded to each other to form a substituted or unsubstituted ring structure, and R1 and R9 may be bonded to each other to form —CRaRb— that crosslinks two benzene rings;
Ra and Rb are independently selected from a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms, a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 50 ring atoms, and a cyano group;
two selected from Y1 to Y3 are nitrogen atoms and remaining one is CR, or Y1 to Y3 are all nitrogen atoms;
R is selected from a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms, a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 50 ring atoms, and a cyano group;
X1 is an oxygen atom or a sulfur atom;
R21 to R27 are all hydrogen atoms;
L is a substituted or unsubstituted arylene group having 6 to 50 ring carbon atoms;
one of R11 to R14 is a single bond bonded to *a;
R11 to R14 not a single bond bonded to *a and R15 to R18 are hydrogen atoms;
X2 is selected from an oxygen atom, a sulfur atom, NRA, and CRBRC;
RA is selected from a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms, a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, and a substituted or unsubstituted heterocyclic group having 5 to 50 ring atoms; and
RB and RC are independently selected from a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms, a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, a substituted or unsubstituted heterocyclic group having 5 to 50 ring atoms, and a cyano group;
provided that when RB and RC are each independently a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, two aryl groups may be crosslinked by —O— or —S—.
