资源简介：
The first spirobifluorenes comprising two
binaphthyl moieties with silicon or germanium at the
site of fusion have been synthesized and fully characterized. X-ray crystallographic analysis reveals that both
molecules have highly distorted structures, resulting in
a low barrier for interconversion between the two atropisomers; the barrier was calculated from the temperature
dependency of the NMR spectra.
