The invention provides a stable double-free-radical monomolecular device containing an anchoring group and a synthesis method. The stable double-free-radical monomolecular device comprises a nitrogen free radical (-N) formed by oxidizing-NH through an oxidizing agent, an Au-N-p bridge-N-Au monomolecular junction constructed by utilizing an STMB technology, and a pyridine (-Py) anchoring group. And the nitrogen free radical is positioned between the pyridine (-Py) anchoring group and the Au-N-p bridge-N-Au single molecular junction. Based on the technical scheme of the invention, the single-molecule junction based on nitrogen free radicals is constructed, and the single-molecule junction has the advantages of simple preparation, high junction rate, good stability and the like, and lays a good foundation for efficiently and stably constructing a double-free-radical single-molecule device. 本发明提供了一种含有锚定基团的稳定双自由基单分子器件及合成方法，包括通过氧化剂对-NH进行氧化形成的氮自由基（-N*）、利用STMB技术构建的Au-N*-p桥-N*-Au单分子结、吡啶（-Py）锚定基团；氮自由基位于吡啶（-Py）锚定基团和Au-N
