Paragraph 0030-0033, (2020/03/06)
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.

An operationally simple and metal-free protocol for geometrically inaccessible C5-H halogenation of a range of 8-substituted quinoline derivatives has been established. The reaction proceeds under air, with inexpensive and atom economical trihaloisocyanuric acid as a halogen source (only 0.36 equiv.), at room temperature. Exceptionally high generality with respect to quinoline is observed, and in most instances, the reaction proceeded with complete regioselectivity. Quinoline with a variety of substituents at the 8-position gave, exclusively, the C5-halogenated product in good to excellent yields. Phosphoramidates, tertiary amides, N-alkyl/N,N-dialkyl, and urea derivatives of quinolin-8-amine as well as alkoxy quinolines were halogenated at the C5-position via remote functionalization for the first time. This methodology provides a highly economical route to halogenated quinolines with excellent functional group tolerance, thus providing a good complement to existing remote functionalization methods of quinolin-8-amide derivatives and broadening the field of remote functionalization. The utility of the method is further showcased through the synthesis of several compounds of biological and pharmaceutical interest.
