摘要： Provided is a carbon dioxide reduction composite catalyst, comprising an organic-inorganic porous body, and a molecular reduction catalyst combined with the organic-inorganic porous body, wherein the organic-inorganic porous body includes metal oxide clusters, and a light-condensing organic material as linkers between the metal oxide clusters, and the linkers absorb visible light to form excitons, and move the excitons through energy transfer between the linkers to transfer the electrons of the excitons to the molecular reduction catalyst.

摘要： An iridium phosphorescent material comprises an iridium-containing core metal and a phenyl-pyridine ligand which is a bidentate ligand of the central metal and in which a steric hindrance phenyl group is introduced, wherein the steric hindrance phenyl is introduced at the ortho position of the phenyl group of the ligand. The present application relates to an iridium phosphorescent material comprising a phenylpyridine ligand in which a steric hindrance functional group is introduced, a method for preparing the same, and the photophysical properties of the material.
