The use of nucleic acid bases (adenine, guanine, cytosine, thymine, and uracil) and DNA polymers in organic light‐emitting diodes (OLEDs) is discussed by A. J. Steckl and co‐workers on page 7552. NB small molecules form excellent thin films by low‐temperature evaporation, enabling seamless integration into vacuum‐deposited OLED fabrication. NBs affect operation through charge‐transport control based on their electron affinity trend: G < A < C < T < U. Appropriate NB selection for electron and hole‐blocking results in enhanced OLED performance.
