| Abstract: | A hexaazatriphenylene (HAT) derivative (compound 1 ) that bears four n‐octyl chains and two thienyl groups was designed and synthesized. Further light‐induced oxidation coupling reaction led to thienyl‐fused compound 2 . Their photophysical and electrochemical properties and self‐assembly behavior have been investigated by UV/Vis, fluorescence, and 1H NMR spectroscopies, cyclic voltammetry (CV), scanning electron microscopy (SEM), and powder X‐ray diffraction (PXRD). Although the difference in compounds 1 and 2 only lie in one single bond that connects the two thienyl segments, they displayed remarkably different properties, revealing an interesting structure–property relationship. |
