The delocalization of electronic excitation energy and excimer formation between bases in B‐DNA were studied using the duplex assembly A1 , see graphic. Through selective replacement of adenines by the structurally similar, but fluorescent, 2‐aminopurine base, these investigations could be carried out by optical spectroscopy at room temperature.
