This study aims to investigate the application of perylenetetracarboxylic dianhydride (PTCDA), which is also known as C.I. Pigment Red 224 (PR224), as a carbon precursor. PTCDA has a stacking structure and planarity, thereby forming a crystal structure and good thermal stability. Moreover, PTCDA has a very high theoretical elemental carbon content of 73.47%, which suggests that its maximum theoretical carbon yield is more than 70%. Therefore, PTCDA was selected as a carbon precursor and compared with coal-tar pitch and petroleum pitch, which are carbon precursors with high carbon yield and excellent carbon crystallinity after carbonization. The initial decomposition temperature of PTCDA was 240-328 °C higher than that of the pitches, suggesting that the thermal stability of PTCDA is better than that of the other pithces. After carbonization, the graphite (002) interplanar distance (d 002 ) of carbonized PTCDA (C-PTCDA) was 3.54 Å, which was similar to that of the pitch-based carbons. The crystal size (Lc) was the largest among the prepared carbons with 30.03 Å. The I D /I G ratio of C-PTCDA was 2.12, which was the lowest value among the prepared carbons. The 2D peak of C-PTCDA was observed at 2720 cm -1 , suggesting the least disordered graphite structure. Therefore, we believe that PTCDA has excellent potential for use as a carbon precursor for highly ordered carbon materials.
