New ortho-phenylene ethynylene oligomers are shown to fold into helices of up to two full turns. Evidence of folding is shown by both 1D NMR, where π-π stacking is explored through both solvent and temperature titrations, as well as by 2D ROESY NMR which

Oligomers based on an o-phenylene ethynylene (oPE) backbone with polar substituents have been synthesized using Sonogashira methods. Folding of these extremely short oligomers was confirmed via 1D and 2D (NOESY) NMR methods. Utilizing electron-rich and el
