Supplementary Material

All chemicals were obtained commercially from Aldrich and/or Merck companies that were used without further purification. Melting points were measured on a SMPI apparatus. 1H and 13C NMR spectra were recorded in DMSO-d6 or CDCl3 solvent on a Joel 90 MHz or a Bruker 400 spectrometer. Infrared measurements were performed on a Perkin Elmer spectrometer. Molecular weight distribution (polydispersity index, PDI=Mw Mn-1) and number and weight average molecular weights (Mn and Mw) of the poly (N-ethylnaphthyl-2, 7-disulfonamide) ) were determined by GPC (gel permeation chromatography) measurements on a 150 Waters GPC system (mobile phase: THF; flow: 1.0 mL min-1 and column temperature: 30 °C). The TGA thermograms of the poly (N-ethylnaphthyl-2, 7-disulfonamide) and PBNS were obtained in a nitrogen atmosphere, flow (200 mL min-1) ramping at a heating rate of 5.00 °C min-1, in the range 30-950 °C.
