A method of synthesizing a fused heteroaromatic compound includes obtaining a first intermediate from a first compound represented by Chemical Formula 1 and a second compound represented by Chemical Formula 2, obtaining a second intermediate including a ring having a chalcogen element from the first intermediate, and obtaining a fused heteroaromatic compound by a cyclization reaction of the second intermediate.
Novel heterocyclic materials are disclosed. The materials contain a fused tetracyclic structure that can improve the properties of OLED devices when the novel heterocyclic materials are incorporated into such devices.

A method for producing a heterocyclic compound represented by general formula (2) from a heterocyclic compound represented by general formula (1) (in the formulae, X1 represents a halogen atom; each of Y1 and Y2 independently represents an oxygen atom, sulfur atom, or selenium atom; each of R1 and R2 independently represents a substituent; m and n respectively represent the number of substituents R1 and R2, each of m and n representing an integer of 0-4; and when m and n are 2 or higher, R1 and R2 may be the same or different and may bond to each other to form an optionally substituted ring).
