| 中文摘要 | the efficient synthesis of (tms)(2)-[7]helicene (rac-3) and double helicene, a d-2-symmetric dimer of 3,3'-bis(dithieno-[2,3-b:3',2'-d]thiophene) (rac-4) was developed. the crystal structures of 3 and 4 show both strong intermolecular pi-pi interactions and s center dot center dot center dot s interactions. uv/vis spectra reveal that both 3 and 4 show significant pi-electron delocalization. |
