Abstract
A polybenzodifuran ladder polymer is disclosed.
Claims16
A process comprising:
- polymerizing a bisalkynyl-tetraoxybenzene (BATB) molecule to form a first polymeric material;
- and
- subjecting the first polymeric material to iodine-promoted cyclization conditions to form a polybenzodifuran material having two aryl-iodide functional handles per repeat unit, the polybenzodifuran material having the following chemical structure:
- wherein R represents an alkyl group and wherein n represents an integer greater than one.
A process comprising forming a polybenzodifuran ladder polymer from a polybenzodifuran material having two aryl-iodide functional handles per repeat unit, the polybenzodifuran material having the following chemical structure:
- wherein R represents an alkyl group, and wherein in represents an integer greater than one.
A polybenzodifuran ladder polymer that includes at least one repeat unit selected from the group consisting of a benzodifuran-dicyclopentadienone repeat unit, a benzodifuran-pyrrole repeat unit, a benzodifuran-dione repeat unit, and a benzodifuran-quinoxaline repeat unit, wherein the polybenzodifuran ladder polymer is formed from a polybenzodifuran material having two aryl-iodide functional handles per repeat unit, the polybenzodifuran material having the following chemical structure:
- wherein R represents an alkyl group, and wherein in represents an integer greater than one.
