A new approach for a compact annulation of tetrathiafulvalene (TTF) and dipyrrolylquinoxaline difluoroborate (QB) is presented, leading to strong electronic interactions between the TTF and QB units. Regulation of distinct photoinduced charge flows within this dyad is achieved by external stimuli, which is also verified by TD-DFT calculations.
