dc.description.abstractThe strategic synthesis of a novel supramolecular 'block copolymer', a polyrotaxane with a triblock architecture was demonstrated. The block polyrotaxane consisted a middle block of multiple γ-CD rings and two flanking blocks of multiple α-CD rings, where all CD rings were threaded on the poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymer with two 2,4,6-trinitrophenyl groups. GPC and H NMR spectroscopy were used to determine the molecular characteristics of the starting PEO-PPO-PEO triblock copolymer. It was observed that five long-chain and nanometer-sized wires, corresponding to the triblock polyrotaxane were distributed homogeneously on the graphite (HOPG) substrates. It was concluded that this strategy could be used for copolyrotaxane synthesis with other macrocycles and copolyrotaxane can be used as precursors for designing advanced materials with different functional properties.
