Abstract
Polyacetylene compounds and process for the preparation thereof from a chiral dihydroxy amide are described. The compounds preferably have diacyl groups attached to the amide. The compounds are useful for making films which are electrically conductive, near infrared absorbing, polarizing, and have the characteristic optical and other properties of polyacetylenes.
Claims6
A process for producing an ordered polydiacetylene compound with two side-by-side carbon chains and aligned diacetylene groups in each chain which comprises:
- (a) reacting a 1-N,N-dialkylaminoalkyl-3,4-dihydroxyalkyl amide with an acyl halide in a reaction mixture to produce 1-N,N-dialkylamino-3,4-di(acetyleneoxy group)alkylamide as the ordered polydiacetylene compound, wherein alkyl in the dialkyl amino is between 1 to 6 carbon atoms and the acetyleneoxy group is between 6 to 50 carbon atoms in a linear alkylene chain with the diacetylene groups;
- and
- (b) separating the ordered polydiacetylene compound from the reaction mixture.
A process for producing an ordered polydiacetylene compound with two side-by-side chains and aligned diacetylene groups in each chain which comprises:
- (a) reacting a single chiral 1-N,N-dimethylaminoethyl-3,4-dihydroxybutramide with an acyl halide in a reaction mixture to produce 1-N,N-dimethyl amino-3,4-di(diacetyleneoxy group)butramide as the ordered polydiacetylene compound;
- and
- (b) separating the ordered polydiacetylene compound from the reaction mixture.
A process for producing an ordered polyacetylene compound with two side-by-side carbon chains and aligned acetylene groups in each chain which comprises:
