We demonstrate herein a facile synthesis of a series of highly-ordered low-melting proticionicliquids with linear C16–C20 side chains identical to natural fatty acids, which were produced by the S-alkylation of the 2-mercapto-1-methylimidazole (methimazole) ring. There is considerable structural latitude possible when designing highly lipophilic proticionicliquids that exhibit low Tm values due

Defying conventional wisdom: Ionicliquids (ILs) with long, unsaturated alkyl appendages (see top structure) defy established trends that link long ion‐bound alkyl groups to higher melting points. The new ILs are also less viscous than a saturated standard (see bottom structure) at the same temperature. These features parallel those that underpin homeoviscousadaptation in certain organisms and are
