Provided are an electron donor-azo-electron acceptor compound having a thiol-based anchoring group, a method of synthesizing the compound, and a molecular electronic device having a molecular active layer formed of the compound. The compound for forming a molecular electronic device includes an azo compound that has a dinitrothiophene group and an aminobenzene group having thiol derivatives.
