Abstract: 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. The compound forms a molecular active layer in the molecular electronic devices. The molecular active layer is self-assembled on an electrode using the thiol derivative in the azo compound as an anchoring group. The molecular active layer in the molecular electronic device forms a switching device switching between an on-state and an off-state in response to a voltage applied to electrodes or a memory device storing a predetermined electric signal in response to a voltage applied to the electrodes.
