Abstract: To provide a method for joining metal members, in which joining can be performed at relatively lower temperature, and deformation caused when joining the metal members can be reduced. The present invention includes a step of joining a plurality of metal members with a sheet sandwiched between the joining surfaces of the plurality of metal members, wherein the sheet is obtained by forming an organic acid metal salt film on the surface of a metal sheet; wherein aluminum or an aluminum alloy is used as the metal members, and a sheet made of any one of zinc, copper and magnesium is used as the metal sheet.

Abstract: The present invention discloses a polymer containing 1,2,5-benzoselenadiazole-N—R1-5,6-dicarboxylic acid imide, and a preparation method and use thereof. The conjugated polymer prepared by the present invention has fluorescence, and a relatively wide absorption of sunlight, and thus it can be used for manufacture of an active layer for a polymer light-emitting diode device, a polymer field-effect transistor and a polymer solar cell.
