A naphthobisthiadiazole derivative is represented by Formula 1. In Formula 1, Z is selected from a hydrogen atom, a boronic acid group, a boronic acid ester group, a trifluoroborate salt group and a triolborate salt group, and at least one Z is a boronic acid group, a boronic acid ester group, a trifluoroborate salt group or a triolborate salt group. The naphthobisthiadiazole derivative is an organoboron compound, and can be converted to various compounds by a Suzuki-Miyaura coupling reaction; thus, is applicable as a precursor of complex compounds. Using the naphthobisthiadiazole derivative, research, development, and practical applications of low molecular weight compounds and high-molecular compounds useful for various organic semiconductor materials and the like can be ensured.
