Abstract
Polyphthalimide nanoribbons (PPINRs) were prepared by the reaction-induced crystallization of monomers, 1-hexyl 4-aminophthalate and 2-hexyl 4-aminophthalate. These monomers were polymerized at 300∼360 °C in alkyl naphthalate oil. The PPINRs obtained were intricately intertwined aggregates of ribbons, and were highly crystalline. The PPINRs were carbonized and graphitized to yield graphite nanoribbons 200∼600 nm in width, which possessed the original PPINR skeleton structure.
