资源简介：
Silicon spiro carbon–sulfur double helicene-like compounds 1 and rac-2 were synthesized from 2,5-bis-trimethylsilanyldithieno[2,3-b:3′,2′-d]thiophene, with total yields of 17% and 7%, respectively. 1H and 13C NMR spectra and X-ray crystallographic analysis showed the predicted 4-fold symmetry for 1 and rac-2 and confirmed their spiro double helicene-like spatial configurations. The absorption behavior of compounds 1 and rac-2 was also investigated.
