## Abstract 1,2‐Dialkyl‐substituted 1,2‐di(2‐thienyl)ethylenes have been synthesized and investigated by cyclic voltammetry. The bulk of the alkyl substituents was modulated in order to progressively increase the torsional angle between the thiophene rings and the plane of the olefinic bond, from a
Poly--amides (nylons 3) were synthesized via the anionic polymerization of a series of 4-alkyl-4-methyl-2-azetidinones where the alkyl group is a methyl, ethyl, propyl, butyl, or pentyl. The "non-assisted" polymerization was conducted under vacuum, in the bulk, at 160°C, using potassium 2-pyrrolido
