Organic light‐emitting diodes (LEDs) with small turn‐on voltages are fabricated here using molecules based on the tetrakis(4‐styryldistyrylbenzene)methane framework (see Figure). The synthesis of these molecules is reported, their absorption and luminescence properties are compared, and the effect of device architecture on performance is investigated.
