The invention provides an organic double-free-radical monomolecular device stable at room temperature and a preparation method, the organic double-free-radical monomolecular device comprises an anchoring group and double free radicals, the double free radicals contain two unpaired electrons, the two unpaired electrons are obtained by oxidizing-NH through an oxidizing agent, and therefore organic conjugated double free radicals are formed. Based on the technical scheme of the invention, the organic double-free-radical single-molecule device can be stable at room temperature, and the conductivity value of the compound before and after oxidation is obviously changed, which proves to a certain extent that the delocalization range of unpaired electrons can improve the conductivity of the single molecule. 本发明提供了一种室温下稳定的有机双自由基单分子器件及制备方法，包括锚定基团和双自由基，所述双自由基含有两个未成对电子，两个未成对电子通过氧化剂对-NH进行氧化获得，从而形成有机共轭双自由基。基于本发明的技术方案，有机双自由基单分子器件能在室温条件下稳定，且化合物氧化前后的电导值变化明显，这在一定程度上证明未配对电子的离域范围能提升单分子电导。
