Nitrogen sorption and desorption measurements were done at 77 K using a TriStar 3000 from Micromeritics. Carbon black lot: 180049/180052 (21.3 m 2 /g ± 0.75) was used as certified reference material to check the accuracy of the analyzer by triplicate. Result (mean of three estimates): 21.9537 m 2 /g (SD: 0.13575). The degassing temperature for this process reached 100 ºC and the degassing period was set for 20 h. The relative pressure (P/P0) used for the BET determination ranges from 5.4643E-5 to 0.99369 (COF-300 nanoparticles), 5.4614E-5 to 0.99293 (nanorods) and 6.4006E-5 to 0.99281 (COF-300 nanoparticles with aniline).
