Angelw. Chem. Int. ed.: the first metal organic coordination polymer superconductor extended organic superconductor system developed by the Institute of chemistry, Chinese Academy of Sciences

In 1964, little theory, an American scientist, predicted that organic compounds have superconductivity, and their superconducting transition temperature can reach room temperature, which greatly stimulated researchers' enthusiasm for the study of organic superconductors The first organic superconductor (tmtsf) 2pf6 (tmtsf = tetrametallic tetraselenafulvalene) was found in the 1980s Up to now, there are three main types of organic superconductors: organic charge transfer salts similar to (tmtsf) 2pf6, superconductors based on carbon materials and superconductors based on organic benzene compounds Due to the low dimension, strong electron electron interaction and electron phonon interaction of organic superconductors, three-dimensional quantum effect, spin liquid behavior and other novel physical phenomena have been observed in organic superconductors In order to pursue the superconducting materials with higher superconducting transition temperature, it is still an important goal to find new organic superconductor materials Superconductivity and TEM of Cu BHT, Stem characterization (source: angelw Chem Int ed.) recently, researchers from the Key Laboratory of all mechanical and solid research institutes of Chinese Academy of Sciences and the State Key Laboratory of superconductivity of Institute of physics of Chinese Academy of Sciences jointly found that the resistance of Cu BHT thin film was 0.25 It is confirmed that Cu BHT is a superconductor with a transition temperature of 0.25k At the same time, the atom image of Cu BHT was directly observed by stem, which confirmed its perfect kagome structure This kind of Kagome lattice may lead to the spin fluctuation of Cu BHT at low temperature Although the superconducting transition temperature is relatively low, Cu BHT is the first metal organic coordination polymer superconductor Its appearance expands the material system of organic superconductor, which provides a new possibility for the study of organic superconductor The spin disturbance observed in Cu BHT at low temperature also indicates that there may be more novel quantum condensate in Cu BHT Paper link: http://onlinelibrary.wiley.com/doi/10.1002/anie.201707568/abstract corresponding author: Chen Genfu http:// Xu Wei http://people.ucas.ac.cn / ~ 0002212 Zhu Daoben http://
