Abstract

The invention discloses a hydroxyquinolinyl metal organic small molecule cooperation compound material grafted with perylene diimide and aromatic groups, a preparation method and applications thereof.According to the invention, the hydroxyquinolinyl metal organic small molecule cooperation compound material grafted with perylene diimide and aromatic groups is obtained through a Stille coupling reaction and a metal coordination reaction; the metal organic small molecule cooperation compound belongs to branched small molecules, the structure of the metal organic small molecule cooperation compound uses a metal as a core, and a branched chain contains hydroxyquinoline and a perylene diimide and electron-donating aromatic group unit; hydroxyquinoline has high electron withdrawing capacity, the grafted perylene diimide unit is beneficial to improving the crystallization capacity and the electron affinity of small molecules, the electron donating capacity is enhanced by linking the electrondonating aromatic group to the perylene diimide unit, and the push-pull electron effect is easily formed with the hydroxyquinoline; and the structure small molecule and the polymer donor form energylevel matching, so that the structure small molecule is suitable for being used as a small molecule acceptor material.

Description

technical field [0001] The invention belongs to the technical field of organic photoelectric materials, in particular to the synthesis of hydroxyquinoline-based metal organic small molecule complex materials grafted with perylene diimide and aromatic groups, and to the application of such materials in organic field effect transistors, organic solar energy Applications in the field of organic light-emitting technologies such as batteries and organic electroluminescence. Background technique [0002] With the development of social population, the human demand for traditional petrochemical energy such as oil and coal is increasing day by day. In order to solve the gap in energy demand and measure the impact on the ecological environment at the same time, academia and industry have turned their attention to renewable solar energy, that is, using solar cells to directly convert solar energy into electricity. However, although silicon-based solar cells have achieved high efficien...
