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.
Claims9
A method for the pressure-induced crystallization of topochemical cross-linking of conjugated polymers, comprising:
- self-assembling a polytriacetlyene to provide an ordered 3D structure of polytriacetylene aggregate, and
- applying a moderate pressure to the polytriacetylene aggregate sufficient to provide a crystallized polytriacetylene aggregate.
