The successful synthesis of SCPP [8] can be supported by different characterization techniques, including high-resolution mass spectrometry (HR-MS), 1 H NMR, C NMR, 2D 1 H-1 H COSY NMR, 2D NOESY NMR, 2D (H, C)-HSQC NMR, and 2D (H, C)-HMBC NMR (Figures ). The molecular weight of SCPP [8] was determined by MALDI-TOF MS spectrometry. The main peak at m/z 1138.4593 was observed (calculated for C90H58 [M] + : 1138.4538), which matched well with the calculated data. Besides, the crystalline solid can be obtained by slow diffusion of methanol into a SCPP [8] solution in dichloromethane (Figure ). Unfortunately, these crystals are extremely fragile, and the large crystals tend to break immediately once exposed to air. Therefore, so far the crystal structure of SCPP[8] cannot be resolved.
