The chemical structures of the polymers were verified by Fourier transform infrared (FTIR) spectroscopy and solid-state C nuclear magnetic resonance ( 13 C NMR) spectroscopy. From the FTIR spectra (Figure ), CP1 and CP2 exhibit strong peaks at υ = 1640 and 1650 cm -1 , corresponding to the C=O stretching mode. Both polymers also display distinct a C≡C stretching vibration signal at 2180-2190 cm -1 , confirming the successful polymerization by connecting two monomers through a C≡C-bond. In addition, the 728 cm -1 band of 3 assigned to C-Br stretching, is absent in CP1 and CP2, manifesting the completeness of the polymerization reaction. As observed from the Scanning electron microscopy (SEM) images show that CP1 and CP2 have a relatively uniform flower-like morphology (Figure ), constructed from 2D nanosheets. The formation of this morphology can be explained by the synergistic polymerization and self-assembly process of the formed amphiphile polymers through hydrophobic-hydrophobic interaction and - stacking. Such unique morphology is beneficial for exposing more redox-active sites and also minimized diffusion length for the transport of ions/electrons, thus potentially delivering a higher capacity and enhanced rate performance. In contrast, undesirable fine-grained bulk morphologies were observed for 1 and 2, probably resulting from tight molecular stacking, which is confirmed by their high crystalline nature.
