To great (monodisperse) lengths : An improved synthesis of purer ethylene glycol (EG) oligomers allows access to 16‐ and 32‐mers pure enough for multiple incorporation, and also to the longest (48‐mer) discrete EG oligomer yet reported. The high purity enables the first crystallizations and hence the first glimpses of secondary 3 10 ‐helical PEG structures.
