title: Hexaazatriphenylene derivatives with tunable lowest unoccupied molecular orbital levels.
abstract: A series of n-type hexaazatriphenylene derivatives were synthesized by condensation coupling of 1,2-diamines and 1,2-diketones. The study of their photophysical and electrochemical properties showed that their lowest unoccupied molecular orbital (LUMO) energy levels could be effectively tuned from -3.54 to -4.02 eV simply by increasing the number of pyrazine units in their molecular structures.
