Pressure-induced crystallization and topochemical cross-linking of conjugated polymers

DWPI Title: Processing pressure-induced crystallization of topochemical cross-linking of conjugated polymers involves self-assembling polytriacetlyene to provide ordered three-dimensional structure of polytriacetylene aggregate, and applying moderate pressure to polytriacetylene aggregate sufficient
Abstract: Polytriacetylene, a unique conjugated polymer with all-carbon main-chains consisting of alternating double bonds and diacetylene units, can self-assemble into ordered structures under moderate pressures, driven by side-chain crystallization. At higher pressure, the polymer undergoes topochemical cross-linking reactions, resulting in insoluble materials with graphyne-like structural and property characteristics.
Use: Method for the pressure-induced crystallization of topochemical cross-linking of conjugated polymers.
Advantage: The method can self-assemble into ordered structures under moderate pressures, driven by side-chain crystallization, pressure can be utilized to induce chemical reactions in tailored polymer structures, where conventional means such as heat and irradiation are incapable.
Novelty: Processing pressure-induced crystallization of topochemical cross-linking of conjugated polymers involves self-assembling a polytriacetlyene to provide an ordered three-dimensional (3D) structure of polytriacetylene aggregate, and applying a moderate pressure to the polytriacetylene aggregate sufficient to provide a crystallized polytriacetylene aggregate.
