THIN FILM AND COMPOUND USED IN THE SAME

To provide a novel material exhibiting excellent light-emitting characteristics using a heavy metal element having relatively abundant reserve. A thin film containing a compound of Formula (1): wherein Ar1 and Ar2 are each independently a C3-30 aromatic ring; R1 and R2 are a substituent; a and b are each independently an integer of 0 to 12, wherein when a is 2 or more, each R1 is optionally different from each other and two R1 are optionally bonded with each other to form a ring structure, and when b is 2 or more, each R2 is optionally different from each other and two R2 are optionally bonded with each other to form a ring structure; A1 is any of direct bond, —O—, —S—, —S(═O)—, —S(═O)2—, —PR3—, —NR4—, and —C(—R5)2—; R3 is a hydrogen atom or a substituent; R4 is a hydrogen atom or a substituent; R5 is a hydrogen atom or a substituent and two R5 are optionally different from each other; E1 is a monovalent group having 50 or less carbon atoms; L1 is a ligand having 50 or less carbon atoms; c is an integer of 0 to 3, wherein when c is 2 or more, each L1 is optionally different from each other; and each combination of a combination of E1 and Ar1 and a combination of E1 and Ar2 optionally forms a bond; and when c is 1 to 3, each combination of a combination of L1 and E1, a combination of L1 and Ar1, a combination of L1 and Ar2, and a combination of L1 and L1 optionally forms a bond.

Synthesis of dithienobismoles as novel phosphorescence materials

Dithienobismoles having a bismole ring fused with a bithiophene system were prepared by the reactions of β,β′-dilithiobithiophenes with aryldihalobismuthanes, as novel phosphorescence materials.
