Abstract

The present invention provides a film-base electric device comprising an electronic conductive metal organic frameworks (EC-MOFs) film. The EC-MOFs film is used as the active layer of the electric device. The electric device also includes more than two electrodes. At least one of the more than two electrodes is disposed on the EC-MOFs film or the more than two electrodes are disposed under the EC-MOF film. The EC-MOFs film of the present invention is applied to a room temperature chemical resistance type gas sensor with high selectivity and fast response, and has good effects.

Description

technical field [0001] The invention belongs to the technical field of electrical devices, in particular to a film-based electrical device. Background technique [0002] Electronic Conductive Metal–Organic Frameworks (EC-MOFs) materials are an emerging class of conductive porous crystalline materials formed by self-assembly of metal ions or metal ion clusters and organic ligands through coordination bonds. Different from conventional organic semiconductors and inorganic semiconductors, EC-MOFs are a new class of crystalline materials that combine porosity, selectivity and semiconductor properties. The reported conductivity of EC-MOFs has reached 50S cm -1 , exceeding conductive carbon materials widely used in electrical devices, including activated carbon. Among them, Yaghi and his colleagues first synthesized a class of EC-MOFs materials with good chemical stability Cu 3 (HHTP) 2 (HHTP=2,3,6,7,10,11-hexahydroxytriphenylene), its conductivity is 0.20S cm -1 . In additi...
