Заглавие : Dibenzo[ f,h]furazano[3,4- b]quinoxalines: synthesis by intramolecular cyclization through direct transition metal-free c-h functionalization and electrochemical, photophysical, and charge mobility characterization Место публикации : ACS omega. - 2020. - Vol. 5, № 14. - С. 8200-8210 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Herein, we describe the synthesis of unsymmetrically substituted dibenzo[f,h]furazano[3,4-b]quinoxalines by intramolecular cyclization through direct transition metal-free C-H functionalization. The electrochemical and photophysical properties for several polycycles have been measured. In thin films of the dibenzo[f,h]furazano[3,4-b]quinoxalines, hole mobility is in the order of 10-4 cm2 V-1 s-1. The results show that the HOMO and LUMO energy levels are appropriate for using the compounds as hole-transport materials in thin-film devices, in particular, organic and perovskite solar cells.
